Commodore 64 C64 1541 Floppy Disk Drive Diagnostics Cartridge

1541 Diagnostic Cartridge

Combination of the Cartridge created by C64iSTANBUL and Jani from World of Jani with minor input from me of a 3D printed case.

To paraphrase Jani:

Repairing drives and having to load a test or a diagnostic software from disk is a bit of a contradiction since the drive being tested, or repaired, might not even be able to load a program.

He also addes a variety of tools for different purposes all one place.
