These are the last of my DRI "original" disks.
|
|
|
|
These disks do not have Factory labels, they were in-house disks.
|
|
|
|
Many are development disks for MP/M-86 and contain pieces of code
|
|
in varying degrees of debugging. There are some boot disks for
|
|
DRI in-house computers. There are other disks for different projects.
|
|
|
|
I used 22disk to transfer the files to DOS when possible. 22Disk
|
|
renames CP/M .COM files to .CPM. Four disks may be formatted for a VAX,
|
|
they have 128 byte sectors on track 00 then change to 256 byte sectors
|
|
with a directory on track 6. DRI used a VAX to cross compile the PLM-86
|
|
code. I did not transfer the individual files from these four disks.
|
|
|
|
I also used Teledisk v2.15 to create disk images of all of the disks.
|
|
|
|
Some disks have deleted files that can possibly be recovered if anyone
|
|
wants.
|
|
|
|
I also scanned the disks and included the scans.
|
|
|
|
Many disks had errors but none of the disks here had any errors
|
|
transferring the files. Most of the disks with errors had them on
|
|
track 00 and have no effect on the directory or files :)
|
|
|
|
One disk was totally unreadable but I scanned the label because it
|
|
was labeled strangely.
|
|
|
|
One is serialized (#14) which appears to be a master MP/M-86 v2.0 disk,
|
|
it is serial number M86-000-00001. Along with copies of the disks
|
|
before and after it would probably be sent to an OEM such as ALTOS,
|
|
as written on some of the labels to be copied serialized and sent out
|
|
with the computers.
|
|
|
|
The serial numbers have a simple code, using the above example M86
|
|
stands for MP/M-86, the 000 refers to Pacific Grove, the 00001 is the
|
|
sequence. In a separate archive you will see a disk with serial number
|
|
MS0-000-00001 where MS0 stands for Pascal MT+ with SPP.
