Good point about the CP/M disk - actually it is read just fine with
cpmtools with this diskdef:
# PRO CP/M RX50 DZ format (Perhaps only 79 tracks should be used?)
diskdef dec_pro
seclen 512
tracks 80
sectrk 10
blocksize 2048
maxdir 128
skew 2
boottrk 2
os 2.2
end
So I'm left with figuring out how to pull files off of 12-bit OS/{2}78
disks.
