IBSYS was for the 709/7090/7094. PR150 is not quite accurate. It
was IBM-1410-PR155, for the IBM 1410.
Paul also did recoveries on IBM 1410 diagnostics and IBM-1410-PR108,
another 1410 operating system, and some other tapes as well. (I went with
him to get the tape used in the recovery of the 1410 stuff. ;o)
What was special about what Paul did was that he recovered data from 7
track tapes, and from tapes that were not, at first blush, perfectly
readable. He actually did bit-cell level analysis of the data to recover
it. (To get IBM-1410-PR155 actually took two fortuitously identical copies
of the exact same information -- you talk about luck).
If the CTSS tapes are 7 track, then that is the kind of thing it might
take. But they might be 9 track, too. 9 track tape drives, are quite
common, and it could well be that that is the format of those tapes,
no? Some 9 track drives would actually be portable enough (at 100lbs) to
carry to the facility along with a PC with a SCSI controller to read the tapes.
(I'm a bit far away to do that. ;-) ).
