Add further devices: CMD HD, REU, uIEC, 1541 ultimate

As taken from Glenn Holmer's commentary on https://www.youtube.com/watch?v=jtlAOdJmeDI&t=134s

This is a discussion item. Actual work will happen on subsequent issue items. Here are some initial thoughts:

• an REU would require a full filesystem built, if used as filesystem.
• A further extension for the REU would be a "swap" functionality to swap out tasks in case of low memory (but that's rather ambitious)
• the CMD HD is an IEC device - it should work somewhat out of the box. Extra functionality could be bolted onto the IEC filesystem, like CHDIR?
• SImilarly for uIEC
• I have no idea about ultimate1541

A swiftlink RS232 module is on the way.

I have a C64c with a Turbo Chameleon an SD2IEC and a Tapuino. I also have a modern GeoRAM 512k cartridge. I'm a bit of a novice when it comes to 6502 ASM. I'm still in the process of learning it. But, is there something specific I can test on actual hardware?

Thanks for the offer. You could test the OS using SD2IEC as storage. I just received mine, but did not yet have time to test

I can verify that GeckOS runs on a 64C using µIEC. I tested the master branch using various disk commands and also piping through more, e.g. "cat index.html ' more".
