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
chips:
-D27128A
K8292550
-TM6310
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
>>55235351
Is that pci?
>>55235351
D27128a is Intel erasable eprom. Still looking though
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?
>>55235351
Ayy.
Got a pic of the back?
>>55235453
>eprom
>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
>>55235351
8 bit CGA w/ LPT port.
>>55235351
I really hate being this old but it's hercules - hgc

>>55235478
yup
did anyone find anything
I really would like the jumper info
>>55235351
looks like an ISA parallel/serial card, not a graphics card
>>55235910
I know the difference between a female and male 9 pin connector
>>55235941
so do i, it's a bummer you didn't show a picture of it, though
>>55235562
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
>>55235351
Did you try plugging it in?
>>55235948
It's easy enough to tell it's not based on the architecture.
>>55235973
how do you know
have jumper info ??
>>55235984
pinouts.ru
for all your pinout needs
>>55235994
>pinouts.ru
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
doing a search for hercules cards shows several will very similar layouts, but not the same jumpers
>>55235351
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 ??
>>55236137
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
>>55236182
but im a newbie at arduino, I just copy all of that codes in the windows and run it ??
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
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
>>55235430
it's ISA fuck stick
![IMG_20160624_151603[1].jpg](https://i.imgur.com/NagdS0r.jpg "IMG_20160624_151603[1].jpg")
we done it guys !
>>55235430
Are you a fucking alien?
>>55235479
Look, this guy knows fuck about ancient hardware.
>>55237133
gorgeous
>>55235430
protip: PCI has a at least one notch in the connector (two if it's dual-voltage)
>>55235479
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
