Retro stuff and old computers

What are 8-bit (or 16-bit with 8-bit support) ISA graphics card's with EGA that support MDA monitors? Card's that can do EGA, CGA and Hercules modes on a MDA monitor.

I only know of ATi EGA Wonder, but that's a card what's impossible to track down these days.

And except VGA Wonder

>ISA GPU
What? Never even knew they made those.

I have a diamond s3 at home, but that's pci

You had to output graphics to a monitor somehow before PCI came along, you know.

Never even considered that.

What ports existed before ISA? I'm curious now.

well, not before ISA, but between ISA and PCI you still had AGP, which was dedicated to video cards.

Also, did you check eBay?

Yeah, been looking for days, but I want some knowledge from people who know if it works.

There are lot of cards that can use MDA monitors but only with EGA mode 640x350 and MDA text but can't do Hercules or CGA.

AGP was after PCI, AGP is PCI with more power and faster link, backwards compatible even with a passive adapter.

There are a lot of old slots, specially for different computers, Amiga, Macintosh, PC-Compatible, etc for all kinds of cards and expansions.

Thanks for the link. That's really interesting.

I have this 8bit graphic card that doesn't output any video, only composite out works

those white labeled chips get hot very quick, what are they used for

also do mono TLL monitors only start up when they recive a signal ??,

got a Philips BM7923 13" AMBER monitor and when I turn it on I dont hear anything, does it need a signal to start up ?? t has a 9 pin connector input ?

It's a ATi Graphics Solution plus.

Might be you'r dip switches are wrong and that's why a monitor won't work, because it supports MDA/CGA and EGA monitors.
You have to find a diagram (or try your luck and test it randomly) for the switches and configure it right, it's just a few minutes work, good luck.

It is a CGA card supporting CGA and Hercules also compatible with MDA, CGA and EGA monitors, but you have to manually select what you use with the switches.

Fix, not Plus but SR*, everything else is right.

And those old cards do heat up quite a bit, wouldn't worry.

Also, I found what you need!

just between ISA and PCI

You mean literary between

okay sow is ON considered the down or up position ??

The side with numbers is usually OFF

I can't find any info on your monitor tough, if it's amber it's monochrome I supose? Unless you already know.
Try switch 1 ON and 3 ON and others at the number sides first, if it works you can try CGA emulation and flip switch 1 to the number side too.
Right now your switches are analog monochrome, so yeah, only composite works.

nothing seems to work
gonna have a look at the monitor to see if I can find any obvious signs of problems

but there is no way I can hook up a digital monochrome 9pin to standard vga, if I rewire it a bit ?

It says switch 6 should be ON too, by factory it should be ON.

And there are adapters for 9pin to VGA, but it's not passive.

(9pin out's on those cards are actually digital not analog)

yes I know that

those white labeled chips get very very hot quick and there are identical ones on board and the dont get even worm

what are they ROM ?

The ones with the white stickers are not identical to the ones without.

And they seem some kind of I/O IC not ROM.

Any luck?

Ok my memory is a little hazy as I was only about 7 years old, anyway, our Everex 286 had an 8-bit ISA card and I remember being able to change the video mode between EGA / CGA / Herc but I'm not sure if that was by DIP switch or DOS command. Monitor was 9pin EGA. The card was very similar to this one: recycledgoods.com/everex-systems-inc-ev-659a-pwa-00306-ega-video-card.html . Good luck.

Thanks! I'll look into it!

but they didnt have GPUs. They had a block of memory on the card that would map to the machines addresses. Then you would use BIOS calls and write into that memory. Essentially writing to the pixels directly. Whatever you wrote would then show up on screen.

some of those dip switches probably control what memory addresses it maps to. If it conflicts with RAM addresses, then it wont work. If using DOS or early windows youll have to keep it all under 640k including the video mem

You're welcome. Some helpful person has collected all the jumper settings here: worldwideweb dot arvutimuuseum dot ee/th99/v/v8ISA_i.htm Wow the spam filter really hates me

well I am still unable to get anything out of the 9 pin

quess gonna need to find a 8bit Hercules now, god thats gonna be fun !

trying to revive a philips nms 9100 it seems to work composite out so Computer seems good except the stupid video card

a bit clearer picture

I'd sell you my old Hercules if I'd find a EGA card with MDA monitor support (with CGA and Hercules emulation)

is that an old raspberry pi

yes, made by ATi

That sucks.

Pretty much anything with a 9-pin output and DIP switches supports a TTL monochrome output, this includes most early ATI cards and probably Oak Tech cards too.

I used to have an ATI VIP in my XT before I swapped it back to the MDA card for date matching, probably going to stick it back in now that I have a much more museum-quality system for that kind of stuff though.

There were accelerators, though.

I'm not sure if it fits the bill exactly, but in my IBM 5150 I have an Oak technologies OTI37c card that is able to support Monochrome, CGA, EGA, and VGA.

When I bought it a few months ago, they were going somewhere in the $20 range.
