I have a list of which computers I have sold. I used to do computer sales while in college. The list: Sol-20 (w/Micropolis drives, Northstar drives, Thinker Toys, others) Commodore PET 2001 exactly 1 Polymorphics 8813 the Apple II floor model (ComputerAge put the shop I worked in out of business) Atari 400/800 HP-85 many different types of HP calculators, especially the 41C Ironically, the only one I own is an Apple II and its a IIe, that would include the calculators. I think the only one I would want is a Sol-20, but with either a Northstar or Micropolis disk system. Eric P.S. I updating my collection list as well: http://www.greenbelt.com/chomko/comp_list.htm
