With a bit of hackery, mc1502 how has diskette I/O. This machine had the usual cloned MS-DOS (nee Sigma-Four DOS) and something original called OTS (One Track System), for low-memory (128K) machines. DOS runs, OTS boots but hangs.

I found some games and put them in a 720K disk (default format for this machine). Also included is the 'Immortal Player' (ip73.com) -- a kind of Action Replay for 73 games of 1980s:
