Hi everyone,
I'm planning to expand my MAME-based emulation of Intel MDS-II systems
with the support for double-density floppy disks. In particular, I'm
thinking of emulating the isbc202 floppy controller because its
architecture looks very interesting. This board was based on Intel's own
300
Hi everyone,
does anyone of you happen to know if the i8049 MCUs inside HP85
expansion modules 82937 (HPIB) & 82939 (RS232) have ever been dumped?
The HP part numbers for these masked ROM devices should be 1820-2437 and
1820-2438, respectively.
I'm asking because I'm working on the MAME emulation
