There are few PC-like machines that IMHO are worth
collecting. The
original IBM PC, XT, AT, portable. The PC3270, XT/370, AT/370, etc. And
some of the early clones, like the first Compaq.
Those and maybe some of the PS/2's as well. (On a related note, anyone
remember Leading Edge computers and how the media (Infoworld particularly)
was falling all over these clones?)
