I borrowed the User Friendly cartoon books, and was also loaned a toy radio-controlled car chassis that could make the basis for a small robot.

My Sennheiser HD400 headphones are back in full operation with functioning foam earpads (and I'm in 70s heaven). I have received a copy of "Assembler Routines for the 6502". I ( Read more... )
