I need some help. Im trying to find some to any info on this videocard. Its a no name graphic card and also pictures tells more




it has a lot of jumpers and I want to set it up for digital monochrome,from what I heard it supports Hercules
it must have some info somewhere

>> No.55235430

Is that pci?

D27128a is Intel erasable eprom. Still looking though

>> No.55235477

Yeeah, thr 27128 is an EEPROM, 41464 is memory, the two TTL chips are buffers. The 6310 is what were after. 8bit ISA card I assume is EGA?

Got a pic of the back?

>all those socketed ICs

it's entirely possible this is a limited production / development / testing board, and you probably won't be able to find anything about it if that is the case

>> No.55235484

8 bit CGA w/ LPT port.

I really hate being this old but it's hercules - hgc

>> No.55235757

did anyone find anything

I really would like the jumper info

>> No.55235910

looks like an ISA parallel/serial card, not a graphics card

>> No.55235941


I know the difference between a female and male 9 pin connector

>> No.55235948

so do i, it's a bummer you didn't show a picture of it, though

>> No.55235973

it's not EGA, as pins 1 and 2 are connected on the board
suits CGA, pin 7 is reserved in CGA, but it's used in hercules, so it might be hercules compatible

>> No.55235975

Did you try plugging it in?

>> No.55235977


It's easy enough to tell it's not based on the architecture.

>> No.55235984


how do you know

have jumper info ??

>> No.55235994

for all your pinout needs

I dont need connector info I need jumper info

all the different combinations for jumpers for each modes

But Im also starting to think my monitor might be faulthy, tryed 4 different videocard and nothing and have no way of surely testing the monitor, its a TTL

Can I use a arduino to simulate a TTL signal to be able to test the monitor ?? its a Philips BM7923

File: 184 KB, 1048x666, a.jpg [View same] [iqdb] [saucenao] [google] [report]

doing a search for hercules cards shows several will very similar layouts, but not the same jumpers

>> No.55236088

maybe it's just for setting the IRQ and perhaps memory size (what i presume are RAM chips are socketed, which presumably means they're optional/upgradable)

thats CGA and is color, will my TTL monitor be OK with that ??

>> No.55236182

that's what CGA uses, TTL/RGBI
though i suppose that doesn't gaurantee it's CGA-compatible
MDA, the black and white graphics card, is also TTL

if you have an arduino why not give it a shot anyway, if it sync's then it's not an MDA-only monitor, at least, since MDA uses different frequencies to CGA

>> No.55236353


but im a newbie at arduino, I just copy all of that codes in the windows and run it ??

>> No.55236543

I found a broken solder joint on a power transistor, maybe that will fix it

its a BD202 with A BIG HEATSINK ON IT

It was the monitor all this time and I wasted a lot of time

cant believe it was a s simple as a broken solder joint

>> No.55236853

It is definitely an old ISA bus, 8-bit, monochrome video + parallel port combo. The jumpers were used to adjust the IRQ for the printer port.
Winbond made them
Oak Technology made them

>> No.55237045

it's ISA fuck stick

protip: PCI has a at least one notch in the connector (two if it's dual-voltage)

>> No.55239976

lel, back in the day EPROM was a cheaper way to provide upgradable roms, rather than using flash/eeprom
and socketed RAM chips on a gpu was common for a time, back when you could upgrade your VRAM
