The 820-II 8" samples in my library show
77*1*26*256 and 77*2*26*256

That's fairly conservative, but works out to almost a 1MB for the DSDD
diskettes. Most systems I'm familiar with formatted at 32 x 256 in DD
mode.
I believe that alternative ROMS were also offered by
third parties.
I've found a couple of examples out there.
I believe that there might be source code for the BIOS
ROM for the
820-II wandering around also. There certainly is for the Ferguson
Big Board, which is a close relative.
Would be interested in the "official" sources if anyone can point me to
them.
