1541 RESTORATION:
1541 Diagnostic Cartridge
I have repaired a fair amount of drives, and every time I find myself loading a test or a diagnostic software from disk. This is a bit of a contradiction since the drive being tested, or repaired, might not even be able to load a program. I also have a variety of tools for different purposes and wanted to have everything in one place.
This is why i created a 1541 Diagnostic Cartridge.
The challenge was to get all these tools to fit into a 8K cart. I wanted to keep the hardware simple and a 16K cart would have overwritten the Basic interpreter.
Therefor I have optimized both code and visual on the tools to keep the size down. Some tools are old, others were written from scratch and a few I rewrote in machine code instead of basic. A couple of the tools are still in Basic, but optimized.
The cartridge is an 8K ROM at $8000-$9FFF
You can also use RESTORE to return to the menu.
You may need to send a “I0:” or turn the drive off/on before running further tests if an previous error has occurred.
A Guide about 1541-II DIP Switches:
Commodore’s 1541-II disk drive has a pair of DIP switches on the back to let you change its device number. DOS and Windows computers use drive letters to address its disk drives (usually A: and B:). Commodore used the numbers 8-11 to address them. Here’s how to set the 1541-II DIP switches so you can run more than one drive.
