@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. |
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.
