Gregory's Serverhmm, even if i manage to find the chip, the other problem is that i don't have the ADF file for it. this is the adapter configuration file and it is required to get the card to function. hilariously, one of the folks on dosforum mentions that they have the ADF file, but then they don't share it.

 i found a vintage ad for an older Hercules card. The LPT112 is their custom parallel port chip. no idea what it is doing on this newer video card. maybe they were using it as a GPIO port. @tubetime Almost every third-party MDA adapter I had "back-in-the-day" also had a parallel port. ... and it looks like it connects directly to a DB25 on the card, so that makes sense. @PCOWandre right but what is it doing on a Micro Channel graphics card without a parallel port @tubetime Aah, see, I wrote that reply before seeing the main thread with the MCA card. Interesting. I assume to smaller pin header on the top of the card is VGA feature; do the pins on the bigger pin set trace down to that chip? dumped the ROM onboard and found this at the end. maybe i should ask this guy lol. @tubetime I'd guess the parallel printer port chip is there so game controllers can be attached. @tubetime ftp://ftp.oldskool.org/pub/IBM_PC_BBS |
there's another chip on the board with the same logo. it's not "DI" but it is the logo for Hercules.
