 CP/M-80 was supported.

   Excellent ! Didn't remember.
   Early TP can be had, free, online now.
   V3 was most useful, but even the first two

    As for the original subject ... alas the 6502 stuff DOES seem to have

 The variant he uses is a static core so you can clock it step by step. In
the video he does a cute thing by tying data lines to create a no-op that
then cycles through successive addresses. THe use of an Arduino as sort of
a logic analyzer is interesting too. I don't need another project.

   Haven't had an eprom programmer in a long time alas ...

 Peddle ate Motorola's lunch but later business decisions weren't stellar.

   At THIS point, I'd rather fool with a Z80/clone board,
   something that will run CP/M-80. Alas even a floppy
   interface - or FDDs for that matter - are getting hard
   to come by. Boards may have to have a trick for using
   thumb drives and PRETENDING they're floppies .... not
   strictly purist, but, these days, you've gotta use what
   you've gotta use. There isn't a huge retro market, the
   world is orientated for the newest/latest whiz-bang stuff.
   And just THIS week ... if in the USA you may not want to
   buy anything that comes from China. Expect a "Bolivian
   re-sell/brand market" soon, but not THIS week.
   I'd buy a TRS-80 model III or IV ... but had some bad
