These are reference charts to trouble shoot your Commodore C-64 and 1541.
I have version Reference #4 and Reference #6
This is a CRT file I made for my Easy Flash 3 cartridge.
This crt contains over 25 Commodore 64 utilities which are mostly disk related programs
Below is the file menu and you can DOWNLOAD the File HERE
Then use the ‘P’ EasyProg built in function in your Easy Flash 3 to install this to your cartridge.
Easy Flash 3
First of all you can have EIGHT custom Kernals. I used this for my JiffyDOS, until I bought the actual chips and install them into my C64, that alone is pretty amazing.
THEN you can add Action Replay and Super Snapshot to this. There are three buttons on the end of this cartridge for MENU, Special and RESET. Special is used for the Snapshots.
This is the BOOT MENU.
The third section is for cartridge images (CRT) that you can add to the Easy Flash 3. You have seven slots, BUT that does not mean that you can only have even programs. You can combine dozens and dozens of programs into ONE CRT file.
I use NDEFGUI to do this.
1541 Diagnostic Cart v1.0
This is a group of 1541 disk drive utilities put together into a cartridge format on WORLDOFJANI
The BEST part is that it is FREE, you do NOT have to buy this from Ebay, just download the ZIP file from the above link. THEN upload the .CRT file to your EasyFlash3 cartridge.
I love the Fast FORMAT utility on this and use it often. Also the Speed Check is nice.
