    Commodore 64c Screws

    I lost all the screws to my disassembled C-64C. I had taken it apart to install JiffyDOS. Anyone know what kind they are, or where I could simply buy a set? eBay had nothing.

    Tano Dragon 64 needs Power Supply...

    Not sure this is right place to post this, but since the Dragon is a Coco work-alike... I’ve started bringing my prototype Tano Dragon 64 back to life. I used to work for Spectrum Projects in the early 1980's, and Bob Rosen got a prototype American Tano Dragon 64 from Tano to evaluate. When he...

    Lo-Tech IDE interface for TRS-80 Model 4 running CP/M
