Actually, I was after *all* the ROMS. Primarily I was after whichever ROM
contains the built-in font data, as I was loathe to type it in by hand from
the rather poor diagrams in the MX80-II F/T manual - though I'm half-way
through that now.
That aside, I had an interesting idea late the other night - why not attempt
to *emulate* the actual printer itself by running the real program ROMs???
I'm not sure if there's enough information available to actually achieve that
- but it would be interesting to at least explore the possibilities.
I can't imagine there'd be a terrible amount of I/O in the printer - just the
parallel interface to the computer and a couple of motors and some digital
I/O for the print head pins?!? That shouldn't be *too* difficult to
reverse-engineer?!? Anyone know what processor is in the MX80 BTW???
Anyway, food for thought. And yes, the ultimate aim is to emulate the
GRAFTRAX functionality of the printer. I expect to have the vanilla MX-80
emulation going in some fashion by the end of this w/e if I get enough time
behind the keyboard. ;)
Regards,
MX80 to PS filter would be interesting...
FX80 even better lol
