Hi,
does anyone of you have this card and could dump the ROM chips on it? In case of the "lower" ROM, dumping the 2000h bytes following the adress from DOS might be an easier way (it's a MCM68766 EPROM with a semi-uncommon pinout).
I was recently gifted one of those, sadly one of the EPROMs appears to have come from another system (the other has a XEBEC Copyright message) making the whole card not work (hangs the system after memcheck - even tho I guess running it on a 486 class machine might add to the issue). If I disable the BIOS and attach a floppy to the corresponding port I can see the card accessing the drive, if I enable the BIOS after booting (via a switch) the upper ROM can be dumped fine using DEBUG
Mine is an "ASSY. 104856" in case that's important.
CRC-32 checksums I got (no idea if uploading my dumps would be allowed here):
ROM Low: 4B62FC09 (MCM68766 - 8K)
ROM High: A13276B3 (TMS2732A - 4K)
