There are a couple of others that I wouldn't mind getting but my wife is well satisfied with what I already have. (She's not into computers.) All of these computers are up and running and I'm not sure I have room for many more.
I wouldn't mind a 386 machine though. I still have some of my old DOS software and I even pondered with the idea of setting up a BBS on a 386 using PCboard 15.2, which I still have, just for the sake of nostalgia. I would have to pick up a modem for it though. My 1200 baud crapped out years ago.
I still have GFA Basic for my Atari 1040ST as well. That was a great basic compiler back in the day. It was sold by Michtron in the U.S and Canada. And of course I have a ton of Commodore 64 games and stuff. I have Jiffy DOS installed in the 64C and one of the floppy drives. It really does make a difference in the load time. I also still have quite a bit of games and stuff for the PET. My dual drives for the PET crapped out a couple of decades ago so for now I am using the slooooooowww cassette tape drive.
