>what is composite

Literally me circa 1990

>>4400327
This ffs

22 years olds who play CGA games and roleplay on /vr/ don't know that, silly

>>4400321
I unironically love the purple and cyan

27-year old here, my family could afford VGA but I never did know of a way to alter the appearance of the rare CGA game I'd come across. I'd be interested in an explanation as to what you're talking about.

>>4400485
We never tried connecting that kind of monitor. I never would've known.

My Headstart Explorer certainly had no composite output

>>4400497
That's what you get for buying gimped hardware

>>4400504
Not that anon, but
>THIS produced CGA graphics
Technology sure has improved since then.

>>4400321
>finally have enough money for a home personal computer
>buying a piece of shit what is IBM PC

>>4400508
CGA technology sure hasn't

>>4400527
Maybe he wanted to use it as more than just a toy.

>>4400508
Most of that is just RAM, various character ROMs and the composite encoder. The actual CGA generating side is comparatively small.

>he bought an IBM PC instead of an Atari ST
ROFLMAO

>>4400563
Should have at least said "Amiga". Now everyone knows you're trolling.

>>4400508
you should see all those old 12" long adaptor cards from days of old

>>4400604
That's a lotta card for just an adaptor.

>>4400603
But anon, Atari gives you Power Without the Price™

>>4401089
well im sure convinced now

>>4400343
Nice blog. Where can I unsubscribe?

>>4400481
>27-year old here
No wonder.
You're too young to have experienced CGA in its true for, being the best a PC could do.
When you where born, VGA already existed.

>>4400508
It's off the shelf shit.
Even at the time, if you would have really wanted, you could have scaled it all down to one IC and a few RAM chips. It just wasn't worth it.

>>4400321
It looks better this way anon

>>4401373
>listen to a kid who can't into electronics and wasn't even born when that card came out
lol no

>>4400321
there's also palette 0. I actually prefer this one anyway.

>>4400451
Same here, I want OP to post more CGA title screens

>>4400321
Please post more CGA goodness

>>4403783

>>4400481
>>4401372


I'm 32 and never knew that either.

That said, I Nostalgia like fuck seeing them CGA screens. And like previous anon, I unironically like them.

>>4400504

I want a thread where everybody posts fuck-huge cards for now-primitive tech and we all oooooh! and aaaaah! at the progress silicon has made over the years.

Yep, that sounds pretty comfy to me.

>>4403831
It's not the size of the card it's how you use it

>>4400343
Kill yourself already fag

>>4400441
>22 years olds who play CGA games in DOSBox
these people are the only ones who 'knew' it
nobody using the original hardware at the time did

>>4400321
>Playing CGA games in color.
>Not using a black and white monitor.
Get on my level.

>b/w

>>4403938
I'm sure you're talking from "experience", anon.
Also, "I was 7 years old and no other kids in kindergarten knew it or used it!" is not an argument.

My older brother even had a small TV set up next to the computer just to use it for CGA games and that was in the mid 80's.

>>4403941
Hercules/HGC/MGA was just awesome, the sharpness and dithering was just so beautiful.

>>4403939
This.

>>4401373
This. The only reason the card was this big was marketing reasons.

>>4403951
>>4403938
>>4400441
thank goodness for dosbox and sierra for supporting every graphics option and sound option under the sun so you can run 20 combinations of the game

>>4403961

DOSBox is shite these days, m80.

>>4403964
yeah but where else can i emulate CGA, EGA, VGA, HGC, SVGA, Adlib, SB, disney sound source, and GUS?????

>>4403961
I thank myself for actually having interest in this shit and having every hardware configuration, physically available to run them on.

>>4403967
You don't.
You use actual hardware.

>>4403941
That VGA looks more like EGA.

>>4403970
maybe in 2005 it was easy to get that, but with the rise of nostalgia retro and e-celebs, you're looking at hundreds of dollars to rebuild these machines today

>>4403967

That's the rub of it; DOSBox sux brix, but there's really nothing better that's cross-platform.

>>4403975
What about PCem?

>>4403973
Indeed, hence why DOSBox exists.

>>4403979
Still raw

>>4403967
>>4403961
decisions decisions

>>4403783

>>4403783
skate or die

I can't be the only ones who likes CGA over EGA. It only needs a little desaturation then it will be perfect.

>30 year old
>dad had a 486 with VGA graphics in 1992
>let me play on it all the time, trusted me with it completely
>I had no clue what an absurdly expensive machine he was letting my filthy little kid hands all over

Dude must've been fucking crazy.

>watching lazy game reviews
>literally the only game he ever tests is commander keen

what a faglord, bet that nigger doesnt even play any of the 2000 big box games he has besides sim ones

>>4400321
I was a CGA kid.
The feelings when we upgraded EGA is what I imagine people felt like when they went from black and white tvs to color.
Fucking emotional man.

>>4403960
>early 80s IBM
>doing stuff for anything other than purely functional reasons
>giving a solitary fuck about marketing wank for consumers

Yeah, no

CGA over RGB...

>>4404217
...and over composite from the same CGA card.

Fucking magical if you ask me.

>>4404219
This looks shockingly similar to the VGA output

>>4404217
>>4404219
wtf i love CGA now

>>4404217
>>4404219
You've got to eat your vegetables.

>>4404219
Well, the digital output is not clearly the same as the RGB, and only kinda works with NTSC.

>>4404350
EGA*

>>4404386
Whichever. They're marked as the same mode on the configuration splash screen. I still find it hard to believe that those cards had similar capabilities if you just used the right kind of monitor.

>>4404395
>They're marked as the same mode on the configuration splash screen

VGA is hardware compatible with EGA. And if by "monitor" you mean composite, that's the encoding, which happens inside the card itself. See the rainbow patterns in the subtitle? That's basically the jist of how it works.

The best colors

>>4404217
>eyebrows are black, hair strand is pink
>>4404219
>eyebrows and hair strand are the same color

>>4404434
look at, >>4400375

>tfw nobody posted this video yet

https://youtu.be/niKblgZupOc

For shame

>>4404434
What is output here >>4404217 is not the same image as in >>4404219. If you could get an RGB shot of composite mode, it would be a 640x200 b/w image with lots of stripes.

>>4404453
This explained pretty much everything I wanted to know. For shame indeed. Should've been the second post.

>>4404453
first thing i thought of when i saw this thread surprised it wasnt mentioned till now.

>>4404217
This is what I actually get when simulating composite.

>>4405159
Used this as reference.

Looks like this if I invert the phase, hard to say which one works better.

>>4403939
>>4403952
>not using a black and orange monitor

>>4404219
>Fucking magical if you ask me.
It just seems magic for you because you're a tech illiterate.
It's actually very simple.

>>4404376
Tell him, daddy.

>>4404059
What are you talking about?
It was cheaper to build the card from off the shelf parts then develop and fabricate a custom IC for everything.
The CGA controller was widely variable and used in many other machines.

Latter CGA cards implemented everything into one IC, hence you had small cards with just the controller and memory.

Like said. Marketing reasons.

>>4404217
Because CGA _literary_ only outputted 4 colors.
Sure it had other modes outputting more with lower resolutions, but those where rarely used, even the other palettes where rarely used.

>>4404219
Because composite artifacting is a thing.
Apple II also used it heavily.

>>4400321
>Not having your drunken father buy you a Tandy 1000 EX and getting superior graphics.
Anon, please, go back in time and get a drunk dad.

Some interesting technical reading on the subject of how many colors you can squeeze out of CGA.

>>4400451
s a m e

Doesn't work for everything, but it's a nice palette.

>>4402078

>1080p

>>4404050
The Keen games are actually some of the most useful titles for testing hardware's DOS compatibility. They're very sensitive to the graphics implementation and any hardware that's not fully compliant with the published spec will result in obvious graphics glitches.

>>4406564
I get that, Im just sick of seeing commander keen, over and over in his reviews.

man pcs were so shitty back in the day. Every single picture posted in this thread looks like absolute dogshit.
