Ah, _tape_!  Tell me more about the tape!  It is digital, I presume?
Perhaps a cassette?  Do you have any valid tapes for it?

It may be possible to reverse engineer the tape format, to
enable you to write new tapes from, say, a PC sound card.

BTW, have you had this machine open?  If we knew more
about the microprocessor and the EPROM, it might be
possible to unravel everything about it, with enough work.  ;-)

This would be relatively difficult to use without extensive
documentation.
