   Excellent ! Didn't remember.

   Early TP can be had, free, online now.

   V3 was most useful, but even the first two
   were more than OK. Did a LOT of software
   using those. V3 added good IBM-PC graphics
   capability ... not very useful for Z80 stuff.

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

   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
   experiences with e-Bay ......
