In this episode, I dive into the hands-on aspects of using CP/M on the Commodore 64. I'll walk you through the practical challenges of transferring software, overcoming floppy disk incompatibilities, and finding workarounds like using the SD2IEC device. I’ll also demonstrate how to use ctools and the c1541 utility from VICE to manage disk images, especiallly to deal with both the standard C64 file system, but also the CP/M filesystem hidden on the C64 disks.
Using CP/M software on the C64 is a culprity, especially because of the absence of a native 80-columns text mode. But there's a solution to this problem.
Speaking of problems: I had a look into a CP/M diagnostics program that, despite all my efforts, just wouldn’t work.
And let's not forget about the dreadful speed issues: Working with CP/M on the C64 was a nightmare. But there existed a Fast Loader, which however seems lost in time ...
