By replacing the ROM(s) of a Commodore 1541 disk drive it can be made in a KIM-1.
Well, it runs the KIM-1 ROM modified to use the 6522 driving the IEC bus as TTY serial input/output.
The ROM is also moved to E000 for obvious reasons (the 1541 is unchanged!).
Only serial TTY, no LED, no keypad (code removed), no application or expansion connector.
Tiny basic in the other 1541 ROM socket also runs.
But it behaves like a KIM-1, as Dave McMurtrie shows in the video!
This is a first step to a KIM-1 with a 6522 instead of the 6530 or 6532.
