Oh wow that doesn't seem right at all can you send a picture of the card so we can see the ic chips? […]charlatan wrote on 2022-03-24, 12:17:Boohyaka wrote on 2022-03-24, 12:07:
I don't see why it wouldn't. From what I can tell these cards are extremely basic anyway. When they run fine you completely forget they exist. No need for specific drivers. They just work from DOS, and in all Windows versions they are automatically detected and supported. I never tried it to be fair but I can't see how it could be a problem if the DB25 cable is off.
That's what I thought and it seems logical. Since I wrote that, I took a closer look at the card...
The wiki page states that IC3&6 should be 74LS08N and IC5 should be 74HCT04N. On my board, IC3 (Address Decode & Data Buffer) and IC5 (IRQ Select) are switched around.

I guess whoever assembled the card had a bit of a la la land moment and missed the fact they installed the chips in reverse order.
Shame its not socketed it would be much easier to fix vs desoldering parts.
It certainly appears that way! It’s a bit hard to see but pic attached.
