Glad I’m not alone!
Haven’t acquired any myself yet, but I’d like to. In fact I’m glad to hear you’re having fun with the C64 since I figured that would be my first one.
Recommendations?
The lisp machines are really cool, and I believe the MSX has been mentioned.
However one that I keep coming back to with fascination is the Sharp X68000, a Japanese computer based on the Motorola 68k.
It used hardware very similar to late 80s and early 90s arcade games, and in fact has excellent ports of things like Street Fighter 2.
But the whole aesthetic of it, along with what it could output for graphics and sound - as an outsider, it looks like it was way ahead of the US and UK computers of the time (the closest contender being the Amiga).
Would love to pick one up and try writing some code for it someday, although I expect I’ll need to brush up on my Japanese.
