D27128a is Intel erasable eprom. Still looking though
Evan Phillips
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?
Jack Davis
Ayy.
Got a pic of the back?
Landon Mitchell
>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
Leo Bailey
8 bit CGA w/ LPT port.
James Garcia
I really hate being this old but it's hercules - hgc
Dylan Mitchell
yup
Lucas Barnes
did anyone find anything
I really would like the jumper info
Jose Watson
looks like an ISA parallel/serial card, not a graphics card
Ian Gray
I know the difference between a female and male 9 pin connector
Anthony Fisher
so do i, it's a bummer you didn't show a picture of it, though
Hudson Garcia
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
Carter Lee
Did you try plugging it in?
Adrian Foster
It's easy enough to tell it's not based on the architecture.
Jace Johnson
how do you know
have jumper info ??
Samuel Jones
pinouts.ru for all your pinout needs
Ian Wright
>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
Jason Nguyen
doing a search for hercules cards shows several will very similar layouts, but not the same jumpers
Jaxon Rogers
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 ??
Colton Torres
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
David Taylor
but im a newbie at arduino, I just copy all of that codes in the windows and run it ??
Carter Flores
I found a broken solder joint on a power transistor, maybe that will fix it
its a BD202 with A BIG HEATSINK ON IT
Noah Brooks
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
Jaxson White
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
Liam Rivera
it's ISA fuck stick
Jackson Moore
we done it guys !
Owen Lee
Are you a fucking alien?
Ian Reed
Look, this guy knows fuck about ancient hardware.
Eli Smith
gorgeous
Carter Bennett
protip: PCI has a at least one notch in the connector (two if it's dual-voltage)
Noah Harris
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
