My collection started eons before Ebay changed the way we trade old computers; unfortunately I
have never been rich enough to dedicate much of my budget to my passion.
It may not seem that big but is well conserved and, above all, is complete and operational and when I mean operational I mean you can sit down in front of one of these oldies and start programming in Pascal, Comal, Logo, PiPs, Fortran, Lisp, Prolog and Occam!
I am not gonna expose my collection here. I will rather put some "howTos" on those machines and their lost dialects and maybe some other stuff. It's called Retrocomputing now, no way: I still feel there is much to be done when I switch on my PET.
