My robotics kit with the Commodore 64 is going well. Hardware and software
works. Gonna make disk images of software for safety. But the problem is
missing parts. Two motors are missing and worm drives. With one motor the
projects are limited. I will post videos of the two projects that I did
today. There are more I can try, but ran out of time. Anyone have any
Capsela motors and worm drives we can borrow?
