The C64 anon from the previous thread here.
My dad said that the company where he works has a shitload of 5.25 floppies (new it seems) and also other old stuff (and sadly a lot of that gets thrashed, or i don't know).
He brought home these ones (for now) and the box is a little damaged, the backside says Made in England.

Also i almost finished the 1541 for now, the fan i put in there started to get a little too noisy for my taste and i will replace it later. Before that i tested a lot of spare chips i had (5x 6502, 12x 6522 and >100 2kbyte SRAM), what failed was a 6502 from Rockwell and 2x SRAM chips from Hitachi made in W. Germany (that was very unexpected).
Today i will test the spare C64 chips by using certain SIDs and test programs and patterns.
Then i will start replacing the video and audio output drivers with opamps after i recorded some references for comparsion.

>"Reliable and durable" written on the box

Man I'd love to still be able to find floppies like this. Now even the "100% tested error free" might not be true.

Anyway, having non-working West german chips is weird, most of the time, you guys make rock-solid stuff (my best 00s floppies are Fugifilm ones made in Germany, and I never had any problems with them).

>Now even the "100% tested error free" might not be true.
I tested one. Works perfect.

>having non-working West german chips is weird
Yes, quite disheartening.
Trust me, i even applied some solder on the pins to give them a better connection to the socket. As i had to reseat many SRAM chips multiple times to get them working (used an old precision dil socket). Each chip was tested one at the time, and i read the directory of my copied test disk to verify that the chip works for a few minutes. I spent 5 hours testing all chips that fit in there, but now i know what works and what doesn't.

Also using some diagnostic programs.
This one:
Gives me the same errors as you can see in the screenshot (it's animated), should i worry about this?

So i tested the 2 spare VIC-II i found recently.
The one that came with my C64 is 6569R3 2084 (left), the 2 i found are R3 1585 (middle) and R5 0989 (right).

While BASIC doesn't seem to look that different, but this one sure does.

On the previous thread i mentioned my theory why modern TVs show the C64 S-Video with some sort of checkerboard pattern.
It's all about the odd habit that modern video equipment has. They demodulate the chroma they get and remodulate again and substract that perfect sinewave against their source (which is not always a sinewave, especially with /vr/) and take that result and subtract it from luma for what reason ever. On S-Video it makes everything more worse, on composite it may produces a good picture or one with a lot of "jail bars".
On my KV-C2521D which has S-Video support on SCART 2 i see only faint "jail bars" which are still more visible than my NES.
I'm sure this is all because a single transistor does not make a good video amplifier in my experience, a high frequency OpAmp intended for video signals with a very very small phase shift makes an insanely good video amplifier.

Sorry, already stored that one away.
I like to call that setup: "The accident that waits for it's chance."
Doing dangerous (mostly for the equipment) experiments without fucking it up is something i start getting good at.
If the 9V clip slipped off and made contact with anything else than ground then my C64 would be toast but that didn't happened, i just tested that SID for about 15 minutes only and doing anything beyond testing wasn't part of my plan.

Maybe later i will put that chip either in some sort of HW SID player or install it in my C64 and make switchable between 6581 and 8580.

Here's my little story.

I remember when I was 12 or so the first computer or gaming system of any sort we got was this thing my mother called an IBM clone. No clue at all what it actually was, but some friend of the family gave us a bunch of disks with games on them. I thought most were garbage, even back then but there was Jumpman and this weird thing that was like PacMan but in super simple first person perspective.

Then there was this other game, this weird little dungeon explorer that I thought was the coolest thing in the world. Even compared to Jumpman it looked really simple, just ascii characters and letters. But every time you went in, the whole dungeon and all the items were different and it was hard and scary as fuck. I would find a scroll, read it and just hear maniacal laughter in the distance. Then inevitably an Ibis or a Kestral or something would find me and slaughter me. I felt accomplished in any run where I could even make it to the second floor. But ohh how I loved it and I would play for hours at a time.

The game of course, was Rogue and very famous. But I had no idea back then and for many years I just thought it was some weird random game like the others that was largely unknown and forgotten by anyone. It was only in the mid 00's that I discovered it not only wasn't forgotten but had spawned an incredible genre all on it's own.

I couldn't remember at all so I went digging and found it! The game was called 3Demon. This was it, not a great game but back then I thought it was super impressive.

I do play roguelikes now, I haven't gotten very into any of the really big complex ones like ADoM or IVAN though mostly because of a lack of time. It took me almost two years to really get good at POWDER which is one of my favorites because it's a straight dungeon crawl like Rogue was but with some really interesting systems.

I also really, really like Shiren the Wanderer. It was great after playing the DS port to go back and play the Super Famicom version and have even nastier surprises.

Both the ST and the CPC use a CPU that was used in countless arcade games (MC68k for the former, Z80 for the later), the same soundchip (AY-3-8910), and both received countless arcade ports too, so it's still surprising to find out that MESS don't support them correctly (according to the other anon).

Yes, but it will be hard to have these switchable and heatsinked.
I'm also not interested to apply solder to them, and i'm not sure how construct this at all.

My attempt to improve the sound of the SID was quite a success, it doesn't sound radically different but the high frequencies (about >5khz) are little louder than before and overall it does sounds better if i play older recording on one channel and the newer on the other channel. The newer recording will always have more 'depth' compared to the older one.
I used a LF356 as voltage follower and 100 ohms as output resistance.
Changing the audio input circuit to that what the earlier C64 used (100nF to ground, 1µF AC coupling) has reduced background noise a little.

If someone wants these 18 recordings, tell me where to upload and which format (stored them in WAV, i have too much free HDD space).

Now i went through the effort to replace the video amplifiers with 2 quite expensive AD810 video opamps.
It was worth it.

Now this is the same 6569R5 as in >>2237447

The vertical lines are worse in composite but i have idea for that:

There's that trick to invert the source signal of the interference and add it to the video signal to cancel it out. It will be tricky to do that on my opamps as the inverting input is very sensitive.

I also forgot to turn off the chroma shift setting in these (need that for my other capture device), also the Automatic Gain Control (AGC) in my capture device was on and might influenced the real difference.

The reason why this is brighter is because i paid attention to the AGC of my capture and kept turning it on and off to see how well the video levels are set, an oscilloscope would saved me that trouble.

I observed that my SID warms up to around 40°C while the rest stays about 30°C.
So, i went full /g/ and added a tiny ass fan next to the SID. It's very quiet because it runs of 5V.
The only thing i don't like is that i have to use a pullup resistance of 193ohms to get the luma signal right (470ohms and 330ohms in parallel), the preliminary datasheet mentions 390ohms and what's often used is 470ohms.
I have a not so great feeling about this.

The first dumb thing i did about the video amp was to use the unregulated 9V like the original modulator, this was beyond retarded as it has a strong 100hz ripple. So i added 4700µF parallel to the original 2200µF one because... i don't know.

I can't install graphics drivers on NT4 on this 770X, the video features diskette said they installed correctly but when I rebooted, it was still using the generic VGA driver.

It's like it's refusing to recognize I installed the driver at all, even though it's all there.

My original plan to feed the interfering signals to the inverting input was quite a failure, it was prone to catch electromagnetic fields from my CRT and i encountered a problem that didn't made any sense: A bare 470kohm resistor didn't seemed to pass the signal while the same resistor in my resistor dial did and i measured in both the correct value, the same weirdness happened with 330kohm.

Time for plan B: Invert these signals with an 74HC14 and couple them via a 2,2Kohm trimmer to the point between the diode that goes to Luma pin of the VIC-II and the pullup resistor. At least this method worked for some people.

Check in the Configure menu, Dip-SW tab if the emulator is in terminal or BASIC mode, and if the FDD boot is in auto instead of disabled.
If it still doesn't work, then ROM files do you have? You should have at least a "How many Files (0-15)? " prompt when starting up.

Plan B worked, good enough for now but i'm close to finish the C64.

Fully removing vertical lines in the luma output of the VIC-II is impossible, so converting it (back) to a digital signal in weird way as in taking advantage that the VIC can only output a few distinct luma voltage levels (6 or 10 depending on revision) and then converting this perfect number back to analogue voltage separate from the VIC.
I could design such a ADC based on many comparators that must be adjusted, but i need 9 of them fast enough (>8mhz) and the rest is logic that involves the pixel clock and a (most likely weird) DAC that outputs the right voltage. Maybe a linear 6-8bit DAC driven by some sort of fast ROM.
Maybe i do this in the future.

Old C=64 Harddrives were SASI drives (an ancestor of SCSI) coupled with a floppy to SASI interface and a ROM with the routines to handle both.

Today, the best thing you can do is check how to use old MFM HDDs on a C64 (I know that the 1580 drives are MFM, so I think replacing a failing 5"1/4 drive by pic related in one of these might do the thing), or just check IDE64 on this link :

>> No.2276437


The link you gave me was what I was thinking of. if I could somehow implement it inside of the system, but I guess I could always just build my own external hard disk enclosure to match it. I found this http://members.optusnet.com.au/spacetaxi64/PC-HARDWARE/CIA-IDE-HD/CIA-IDE-HD.html but it apparently only works with GEOS, which I guess is okay, I was planning on running GEOS on it anyway.

>so I think replacing a failing 5"1/4 drive by pic related in one of these might do the thing

I don't think it would, at least it definitely wouldn't work with PC compatibles where MFM disks require a dedicated controller.

That would definitely please the fuck out of my autism if I could fit an ST-225 in one of these, though.

speaking of autism, I got bored and decided to try doing a mockup of an IDE enclosure based on a 1571, I definitely like this idea better than just mounting one in the case.

Many of those games had an option in the config for EGA/CGA/VGA graphics, depending on what your hardware looked like. If you aren't familiar with what those mean, look them up.

I'll just make it 640x480 with all the sprites made at half-size then scaled up. Then if someone plays fullscreen it will keep the same aspect ratio and leave black bars on the sides if necessary.

I just received my Action Replay cartridge.
It has a 27C256 EPROM (i peeled the sticker a little off) which i dumped and has a custom logic chip which isn't that what i really wanted. Oh well at least i don't have to wait very long for my floppy disks now, and i may save or pause whenever i want it.
The dump matches with "Action_Replay_V4.2_4.0_1988_PAL_v2" from rr.c64.org , they mention that all ROMs have certain software bugs.
I would like to know them and if there's any kind of fix/patch/hack for these.

I also improved the transformer in my 1541, if it was supposed to buzz loudly when it got hot after few hours of operation.
My first attempt with covering both primary and secondary windings with hotglue worked very good just when it was liquid but as soon it dried the transformer just buzzed half as loud.

ST devs should have supported MIDI devices more. I mean, those MIDI IN and OUT ports were THE killer features of the ST, not the 16 color graphics that you could already find on older computer systems.
I know that Sierra and a few other devs allowed ST owners to use an MT-32 or other external MIDI expanders for the game's musics, but the amount of games that supported this kind of enhancement was pretty low compared to the amount of IBM-PC & clones or x68000 ones, which is too bad as these don't even come with integrated MIDI ports (though Geograph Seal do support the use of MIDI expanders directly hooked to the RS-232 port)
And it's not like MIDI sequencer and patch editors lacked, the ST was the platform that made both Cubase and Notator popular, and utilities like pic related (yeah, this version was released in 2014, but the original was made in 1991) allowed musicians to edit FM patches the easiest way possible. There was this Sound Canvas utility available too.

3 voice synthesis sound chip + garbage graphics chips vs. Amiga's 4 channel sample based sound + superior graphics chips is what killed the ST for mainstream.

Naah, what killed the ST for the mainstream was the lack of killer feature/soft for the this domain. Look at what happened to the Amiga in the US -- it got beaten by a machine that could only handle 4 colors at the same time and make a buzz, because the latter could run Lotus 1-2-3 and Word perfect. If the ST had exclusives and/or if devs advertised this MIDI stuff, the platform would have stayed a bit longer.
Also, don't forget that until 1990, the Atari ST sold more than the Amiga.

It's true that I shouldn't have said 1990, as 1987 would have been a better answer, but anyway, the ST didn't sold that bad (maybe in Northern Europe excepted), it's just that it's too bad those features that made this machine special weren't used that much in vidya games.

Remember the anon with the TRS-80 model 100 in the last thread?

I finished the repairs last week.

The big problems were:
>preowners removed 10 function keys and did some other shit, also rebranded it
>4 badly leaked capacitors in the power supply
>leaked NiCad battery

I recently gotten a Olivetti M10 with QWERTZ layout, the same preowners didn't attempt to 'rebrand' it like they did to the model 100. Unfortunately the keyboard was damaged because it wasn't in a protective case, the spacebar is mechanically broken and '.' keytop is gone and the switch for it is damaged.
So i decided to swap all function keys, NiCad battery (didn't leaked, still works), 8kbyte RAM module over to my model 100. I also replaced the leaked capacitors on both computers which didn't seem to effect the operation besides that the corrosion could get worse.

The standard ROM of the modemless M100 is different from the american ones with the modem, it also had a standard 27C256 pinout. I realized this after making a adapter by measuring the pinout against the option ROM, i was quite confused why it didn't started with the adapter.
So i made a personalized version of the american ROM (for better compatibility) with:
>Y2K fixed
>reduced key repeat delay
>customized keyboard matrix

About the absent emblem and backsticker, i didn't liked the idea of making a copy which can be mistook for the original. So i made my own out of printed paper and some transparent plastic from some snapped CD slimcase. The backsticker is just a reworked copy of the original but it's just black on white paper instead of black on shiny silver surface.

Now i'm thinking of reprinting the quick reference (mainly for BASIC), i did not decided yet how to mark this one as 'not original'. Maybe i add "UNOFFICIAL REPRINT:" with the date on the title page.

I was very impressed that the NiCad battery in the M10 didn't leaked and held it's charge fine over days (4.10V when freshly charged, dropped down to 3.78V in 2 days).
Another thing about the M10 i don't understand is how it detects what keyboard matrix to use, the ROM is the same as the VirtualT one and i found out that does have data for multiple keyboard layouts. I even programmed BASIC+ML tool that shows me which key is pressed on matrix directly and after looking into it i realized that the PCB is the same as the QWERTY KB (of the schematic) but how it decides which one to use is beyond me.

I hope i get another M10 so i can fix it.

I also tested my spare chips in the M100, 51 of 52 8085 CPUs were working as well 3x 8155 and the spare ceramic 6402 (UART) i had. It's cool that both computers are thick enough to allow sockets on pretty much all chips. I somehow expected that obscure 80C85 i had to fail, it's made by a company called CALMOS.

Well, it's bitmap like display and the little amount of memory doesn't allow astounding games. But there are some for it.
But yes, i might do some more BASIC stuff. You can see that i wrote something that plots a sinewave on the screen by using the LINE command and wraps around the screen endlessly.
Also the keyboard is very good, i don't know how it compares the legendary IBM Model M but typing on that one is fun compared to every modern keyboard i used.

This reminds me, has anyone made a card for IBM Clones, maybe like an ISA or PCI card that has a variety of the older sound chips used in the 8-bit and early 16-bit micros? The AY, the SID, and so on all had distinctive sounds which I think to this day emulation fails to properly recreate.

The AY-3 certainly has an absolutely beautiful sound to it.

I think I'd have to choose the OPL2. As a musician, I can't believe I'm not choosing something more uniquely "musical", but culturally speaking the OPL2 might be the most important sound chip in the history of video games, and it's hard to knock that.

One of the most common resolutions was 320x200 pixels, at a 4:3 aspect ratio (non-square pixels). The colors could be anything from 4 (CGA) over 16 (EGA, VGA) to 256 (MCGA, VGA). CGA and EGA had a fixed set of colors. With MCGA the palette was 256 colors out of a potential couple thousand (15bit colors)
For the specific palettes I suggest wikipedia, as they give you the exact values and reasoning behind these values.
VGA itself could go up to 640x480 at 16 colors, but that was not used too often, because it looked kind of crappy and performance wasn't useful either.
There were also a ton of less common video modes, so you could get away with a lot, but should look up the technical details of these modes. If I were you, I'd go with 320x200 (or 320x240) with 16 colors (EGA), or 256 colors (MCGA), as these were vastly more common than the rest.

The AR cart worked quite flaky (failed to start sometimes, freeze button crashed the C64) as well as many demos. I also upgraded the AR to 5.1a.
So I figured that the EPROM based PLA was causing that.
Some weeks later the realPLA became "available", the shop owner who sells these had serious health problems since the last year.
I fucking waited more than a month for this.

Mathematica was the last demo I tried with the EPROM PLA, unsuccessfully as it crashed after minutes. With the realPLA it ran till the end.

The freeze button still doesn't work and the fastloader often fails to start either (?OVERFLOW ERROR IN 0) which wasn't really the case with the EPROM PLA.
I guess some little capacitor which had been installed depending on the used PLA chip causes that, I will remove it and see if it works.

You guessed the age of that EPROM burner precisely.
It says 1985 on the PCB and most datecodes of the chips are from mid 1986.

>The freeze button still doesn't work
The problem is that the CPU crashes somewhere between from "switching from Ultimax mode to 8kb cartridge mode" to "start to backup memory for restoring", even if the freezer menu appears it's not possible to view the SCREEN (F7) correctly or to RESTART (F3) where it has been freezed.
Diagnosing this will be fun, could be either the I/O1 and I/O2 or the EXROM and GAME signals.
>fastloader often fails to start either (?OVERFLOW ERROR IN 0)
ROML and ROMH seemed to change to quickly, 100pF to ground fixes that.
I will solder this tomorrow, I just held both capacitors with one hand while typing and pushing switches with the other.
>I guess some little capacitor which had been installed depending on the used PLA chip causes that, I will remove it and see if it works.
Well, close inspection revealed that there aren't such things.
But I wonder if some MOS77xx ICs could cause that, they seem work fine because they're are responsible for other parts of the system.

The first edition is a great thing to own, but even that might not cover VERY early standards, things were changing rapidly even then. The first edition covers 286/386 stuff well, but information about even earlier IBM PC standards is a bit sparse, although there's certainly more in that edition than say the 21st. That said, even in the 21st edition it gives important information about servicing P5 machines, which was a standard nearly 20 years old at the time of publication, so they do a great job at including everything that could possibly be relevant, which is important for a print publication. Let's face it, a book including EVERYTHING about the IBM PC spanning over 30 years of hardware and software would be at least 5 times as long any edition of URP and pointless for the vast majority of PC "enthusiasts" who can only see the good in the most modern systems.

I have an old Texas Instruments teletype that was removed from a Southern California GTE central office in the mid 80's. It hasn't been turned on in about 10-12 years, but it still worked. My dad made a cable for it that converted the weird, proprietary TI connector to an easier to work with DB25.

We used to connect it to a PC with a null modem cable and redirect screen output.

And I'm still having problems with the freeze button.
I very sure that some memory backup routine crashes that writes "ACTREP40" at 0x9F00/0xDF00 in the SRAM to mark that "user data" has been saved. If I tap the freeze button again right after the Ultimax mode is disabled then that string is in the SRAM and freezer menu is shown but not all data has been backed up which is the reason why:
>even if the freezer menu appears it's not possible to view the SCREEN (F7) correctly or to RESTART (F3) where it has been freezed.
So I fixed the 0xDE00 read bug (disconnect /IO1 and put a OR gate of /IO1 and R/W in it's place), resoldered the PLCC44 ASIC and added a pullup resistor and 10nF to ground to the freeze button, all that didn't helped.

So I conclude that either the AR cartridge is fucked or my C64 has still some bugs.
I didn't wanted to buy a another AR cart, so I looked even deeper into the inner workings of the AR4.2 hardware and engineered my own clone out of 7400 logic ICs and added (rather impractical) 32kbyte SRAM and 64kbyte ROM support.

Yesterday I just finished building the clone, out of parts I had lying around.
And it works perfectly and the freeze button still doesn't work which means that my C64 is causing that.

While looking into the code I noticed that most IO accesses go to the CIAs and the remove and test method revealed that CIA2 caused all that trouble.
If pin 17 (PB7) is isolated then the freezer works but I don't get it, this pin only goes to the user port and nothing else should make contact to it.

The power "switch" is probably a header on your mobo somewhere, but that's just a guess going off my knowledge of later (read: ATX) board/PSU design. Without knowing the actual hardware you're using I can only speculate.

>> No.2396085

>The power "switch" is probably a header on your mobo somewhere
nope, not on an AT board, power's switched manually at the PSU on those
been a while but iirc there's a paired lead from the PSU that's meant to be connected to an SPST on-off (non-momentary) power switch, or else a switch actually built into the PSU
if you're using an ATX/AT PSU, you can probably nigger-rig something on the ATX board connector's switching pins

Oh fuck I wondered what that was

What's the exact model you own?

According to some sources some 520 ST PCBs have places for additional RAM chips that are only present on 1040ST models, so the easiest way to have a better use of your ST is to be able to use a soldering iron, put some sockets, and find the exact same kind of RAM chips as already used by your ST. Other 520 ST models (the STe ones) use SIMM RAM sticks.
If everything else fails, you could just try to get schematics for a RAM pack that you'd connect to the cartridge port of the machine.

Anyway, enjoy this computer, it's a really nice one to have, it has one of the best FM patch programming soft around (handles most of the OPM/OPZ/OPP-based Yamaha synthesizer keyboards/module), a bunch of nice games (the best version of Captain Blood if I recall), and is easy to program.

After checking info on the various revisions of this model's motherboard, yes it's needed, there's like 4 revisions of it and the RAM bank aren't located at the same place on the motherboard, nor they use the same chips.

Check this website for more informations on various revisions :

Anyway, you might as well try to make a 4MB upgrade instead of just using 1MB, it's not like in 2015 64kB RAM chips are expensive.

But it does.
It doesn't look like it's shorted with D1 but it is, which explains why this shit didn't worked. If the AR wouldn't set the data pins as output for whatever reason then I wouldn't noticed that and would became very confused in the future why my userport device crashes the CPU.

Now I feel like an idiot.

And the worst of all is that there aren't protection diodes on IEC data and clock lines but the official schematic claims that CR100-CR103 should be there.
I was wondering why the C64 crashed when I unplugged the serial cable.

I often forget that I'm the only one who likes messy wires but at least I used the same type of wire unlike some other projects I did where I used like 5 different types of wires. Also the whole mess does fits into the original case.

During the 60s and up to the 80s, mainframes did record stuff on tape reels, before switching to IT-oriented cassette tape standards (Q-Tape, DAT, LTO and the likes). The kind of reel-to-reel tape drives they used weren't the same kind as the audio ones used for early consumers and/or mastering.
As for the consumer market, these kind of reel-to-reel tape recorders were mostly used by enthusiasts during the early days of hobby computing, or by some people already owning this kind of tape recorders before buying a computer (that wasn't a Commodore one or a Speccy). Most of the time, most of the other users just used your everyday Type I audio cassette tape (computer drives didn't handle chrome very well).

Perhaps one of you knows the game I'm talking about, I hope so.

I had it on the C64, I'm about 95% sure it was called "Labyrinth" or at least that's what was written on the cassette tape, never been able to find mention of a game under that name.

The game was very simple, you would give it some dimensions like 16 wide by 10 high or whatever and it would randomly generate a maze based on those statistics that you would then walk through using the arrow keys in very similar style to pic related. I think the maze was in shades of blue but I'm probably wrong, you could cheat and look at a map if you got hopelessly stuck but you got no score any more and after solving any maze it showed you what the entire thing looked like and how many steps it took you to beat it in, there were no monsters or anything else like that in the maze.

It was wonderfully simple and I've yet to see anything that could hold a candle to it in pure, fun simple gameplay. Anybody know what I'm talking about or better yet knows where I could redownload it?
