Well... since I _have_ a SYM-1, and had the books for it many, many
years prior to locating the computer (like 20 years earlier), I'm
pretty fond of the SYM-1. I also like the fact that the SYM-1 does
_not_ use mask programmed parts (but the KIM-1 does). Other than
that, they are really about the same machine. From a programming
standpoint, I am unaware of any significant differences. I know they
could share peripherals.
Speaking of peripherals, I remember lots of ads back in the day,
including one for an S-100 chassis for the SYM/KIM. I'd love to see
schematics for that, especially since if I ever have one, I'll
probably have to make my own rather than find one in the wild. I have
a few S-100 cards now (something I didn't have back in my PET days),
and it might be fun to do some driver coding for interesting things.
I _do_ have (somewhere) the stuff relevant to hooking Commodore IEC
peripherals (1541, 1520, 1526...) to a SYM. That's another thing that
would be fun to implement... disks and files on a 6502 SBC.
So many 6502 projects, so little time.
