Allow SAVE/LOAD to tape

[unbibium]

The advantage of saving or loading to a tape or audio device, is that you don't have to worry about filesystems.

The disadvantage is that it won't be fast, and not a lot of people in retro computing still have working tape drives.

Implementation options:

• Build a Datasette adapter to some Atari port, and adapt CBM's tape code directly to use it.
• Adapt CBM's tape code to work with Atari Program Recorders.
• Adapt Atari's tape code.

I can't do it myself; I don't have a working tape drive for either system at the moment.

Idea: Assume people on the Atari are using FD emulators and re-route cassette IO to the floppy disk, using the disk as one large serial stream of data.

While far from the best solution it might be a stop-gap measure while other ideas are in the works.

Might be able to divide up the disk into partitions equal to memory size to get more than one cassette image on the disk.

FYI a C64 can read ZX Spectrum tapes out of the box https://www.c64-wiki.com/wiki/Spectrum_Simulator#Features
