Nice to see another competent person on board.
First, we would be glad to have additional source code or commented BIOS listings for this system.
Even with unoffical patches applied and a lot of tweaking, the rainbow.c driver misbehaves under DOS 3 and CP/M ("write error").
I hit a brick wall when it comes to 100% accurate floppy emulation. Some keywords: consistent floppy writes, contended memory, insertion of Z80 WAIT states during floppy I/O.
Drop me a line of you are interested in an unofficial build or the header files currently needed to get a working system...
Read support for floppies, hard disk emulation, and ClikClok are already built in. But there is still a lot to do ;-)
