Another machine I had, a bit later than the C64 was an Apricot..  It didn't do much (for me) but had the first 3 1/2 floppy and IR keyboard I'd ever seen.  Anyone know about what the heck that thing was/did?  The thing was beautiful, even by today's standards, but TBH, I was of the IBM PC and Franklin ACE mindset by that time.  Heh, and 3 1/2 inch floppies were pretty expensive.
