Subject: [midatlanticretro] Data recovery project
I've been working on another data recovery project, for the gentleman
who designed the Quest Super Elf. He had over 100 single-sided 8"
diskettes from 1979-1980, formatted and written on a S100 system under
CP/M 2.2. I imaged the disks with Dave Dunfield's IMD utility, converted
them to binary image files with IMDU, then used the Linux cpmtools suite
to extract the files. Only about a half dozen disks had errors on them,
and enough of the files were duplicated so that I believe we recovered
everything (so far).
This recovery was a lot easier than my IMSAI project, since the disks
were all formatted as single-sided, single density (128x26). I was quite
surprised at the lack of errors on the majority of the disks - they just
don't make 'em like that any more!
