Cool! With bbraun's assistance for the fusebit settings (looks like high = 0xBF, low = 0xDA, ext. = 0xFF), I got the new AVR and CPLD firmware flashed.

I don't have a 128K or 512K to play with (only a Plus if needed), so I don't know how useful this info is, but your new Disk011.dsk and Sys330.dsk images definitely mount OK on my IIci through the floppy emu....
