Once upon a time I had a pallet full of Commodore 64/128's and accessories . I got them from a fellow who used to run a BBS with them. When I moved into my Travel Trailer I had to give up a lot of stuff. I gave them, and my Amiga 3000, away to a fellow in Coos Bay, OR who wanted them.
I miss my old Commodore 64/128. It was the last computer I really understood. I had the expanded manual and had even dabbled in machine level programming.
I had a Vic 20 for a while (traded for some motorcycle tires), but it blew up shortly after I gave it to my Mother. I should have put it on a surge protector.
There were a couple of type-in programs that came with the Vic 20. One of them was a simple line graphics program. I expanded on it, made variations all the way up through my Amiga. Some day, if I ever get a handle on Objective-C, I'll probably write it again for Mac OSX and iOS.
I'd probably pick up a C128, just for the fun of it, except I still live in the TT, and don't have room for more than one desktop computer. As much as I like my iPad, I'm not ready to give up my iMac.
