Interesting Stuff for Old Computers
I have the original IBM Technical Reference Manual, part number 6025005. If you are interested in borrowing it, contact me firstname.lastname@example.org . This is a fantastic reference to the serious beginner into the computer field. This was sold for $50 in 1981 and it's availability at this somewhat expensive but approachable price is why the IBM PC became the standard for personal computing.
PCWEB is a collection of programs to get an old PC on the internet.
GAMES are games oriented to older PCs.
