The disk images in this directory were generated from a set of
original distribution disks provided by a Visual 1050 keeper, Still Christ!
He acquired them through some family hand-me-downs dating back to 
the purchase of a new Visual 1050 in 1985.   The disks
are believed to have been used only minimally and should be
very close to the original distribution disks.  It is likely that 
none of the disks were used at all except for Wordstar to make a 
backup working copy.

The Winchester Setup Disk was obtained separately from Bill Degnan.

The labels on the disks are accurately imbedded in the IMD descriptions
and summarized below.  It appears that in some cases the labels did
not accurately reflect the software on the disks.  For example, the
version number of the Multiplan software is actually 1.06 as displayed
when it is loaded.  The disk label did indicate 1.05 as documented
below.  My assumption is that software updates were included as they
were available, but Visual Technologies continued to use the older
disk labels since they probably had a big stock of them.

Although it is not clear from the label data below, the BIOS version
is v1.4 which includes Winchester drive support.

The disk format is 80 tracks, single sided, 10 sectors per track, 512 bytes per sector.

The .IMD files contain the native ImageDisk images.  The .BIN files contain
the pure binary data that can be used by cpmtools to read or manipulate
the disk contents.

The following format definition can be used for cpmtools:

diskdef v1050
  seclen 512
  tracks 80
  sectrk 10
  blocksize 2048
  maxdir 128
  skew 0
  boottrk 2
  os 3
end
