    I guess there has been some developments in the last 35 years? Any suggestions for a tiny editor on CP/M? Right now I use what I have on Linux and Windows and crosscompile with http://www.z80cpu.eu/projects/78-data-articles/projects/76-mdz80

    Fergusin BigBoard II system diskettes?

    Someone suggested that they might be 8" ones. Anyway, format and bytes/sector seems to matter. This works:

    Fergusin BigBoard II system diskettes?

    OK. We have some progress. The xerox-820 diskettes seem to work. Ie this one: http://bitsavers.trailing-edge.com/bits/Xerox/820/5_inch/130S22100DS_CPMRev3.jpg Boots up CP/M just fine. So why can I not write the BBII images??
