I've been testing the GRiD Compass 1101 emulation, am honestly very impressed, and I never thought I'd be using a Compass again, even in emulation.
I've been able to use the 2102 portable floppy.
The 2101 hard drive wants to work, but it looks like the format command is not implemented. I think if I could get the disk images I have here into a serviceable format, it would work...
Who's working on this? I would like to help get this working so that those who can't spend $10,000 on an eBay Compass can actually do stuff with the unique operating system (of which I spent time in contemperaneously both as a user and developer)
