I don't think so. It's a Vulcan IDE card, most of the chips are 14, 16, and
20 pin DIPs except for the EPROM and an MCM6064p12, which I'd guess is some
sort of memory chip.

Looking thru the ROM code with a hex editor, I saw a name, which I looked up
on the web. It seems to be the name of the programmer who wrote the
assembler, S-C Assembler, not the person who wrote the firmware. There is
also an S-C Disassembler, which I downloaded (it's now freeware). I've taken
a few programming courses over the years, but not assembly language, but I
have the general idea. If I can figure out how to convert the machine
language from the EPROM into assembly language with the disassembler, maybe
I can make some sense of it.
