Old AI-KA and OZ Tapes and What to Do with Them
|
|
|
|
Boxes 1-7 contain old AI incremental tapes. These should be thrown out
|
|
without question; they are too used to be reliable. In Box 8, tapes
|
|
AI336-AI350 are also incremental and should also be tossed.
|
|
|
|
Boxes 8-110 contain old AI full dumps, AI600-AI3085. I would not re-use
|
|
any from before tape AI2558 (Feb. 1980); the earlier ones are too old to be
|
|
reliable. In these boxes the following tapes are GFR tapes (like ARCH or
|
|
MIGR tapes from Twenex):
|
|
1264, 1265, 1301, 1334, 1335, 1367, 1407, 140
|
|
and should be treated however the explicitly-labeled GFR tapes are.
|
|
|
|
Boxes 110-111 contain GFR tapes GFR1-GFR32. It would be kind of nice to
|
|
preserve these, just in case anyone ever wants the info enough to pay for
|
|
IPS to read it, or something. They should not be re-used; they are too
|
|
worn to be reliable.
|
|
|
|
Boxes 111-112 contain a number of random personal tapes; as far as I am
|
|
concerned they are re-usable, modulo age and wear.
|
|
|
|
Boxes 112-158 contain old OZ full dump tapes. These are no older than
|
|
1982, and are the best candidates for re-use after those on the racks (see
|
|
below). Boxes 133, 150, and 151 do not exist; I emptied them while
|
|
choosing OZ full dumps to save.
|
|
|
|
Boxes 158-159 contain some blank and recopied OZ MIGR dumps. Do not re-use
|
|
any which have already been used; throw them out.
|
|
|
|
Consider the racks by the wall to be numbered as follows:
|
|
|
|
1 2 3 4 window
|
|
9 8 7 6 5 wall

Rack 1 contains the OZ full dumps Laurel desinated for re-use. I have no
|
|
quarrels with these.
|
|
|
|
Rack 2 is now empty.
|
|
|
|
Rack 3 contains the newer OZ tapes now being saved (June 86-June 88), while
|
|
Rack 4 contains the older ones (July 82-May 86). We are currently saving
|
|
the following from before 1985:
|
|
full dumps from July 82, July 83, and June 84
|
|
SRC and TINMAN dumps of Jan84 (last dumps before merger into PS)
|
|
first KANSAS dump (Nov 84)
|
|
last extant VISION dump (also Nov 84)
|
|
i wish laurel had asked me about which tapes to save before she started
|
|
re-using them, since the last VISION dump should have been saved, but done
|
|
is done. the principle is that while SRC, TINMAN, and VISION no longer
|
|
existed when the machine died, they were valid structures when they did
|
|
exist, and so contained real files that people might care about.
|
|
When you decide to compress the OZ tapes further, the following dumps
|
|
should be preserved:
|
|
those mentioned above, which i saved from the boxes
|
|
Aug 85 dumps (PS F00031 #1-35, SS F00029 #1-4, KANSAS F00005 #1-13)
|
|
June 86 dumps (PS OF0040-49, KANSAS OK0013-17, SS OS0003)
|
|
June 87 dumps (PS OF0114-124, SS OS0010, KANSAS OK0041-44)
|
|
June 88 dumps (KANSAS OK0069-72, SS OS0016, PS OF0203-213)
|
|
|
|
Rack 5 contains another set of AI-KA incremental dumps (AI200-AI350 or so)
|
|
which should be tossed without question, and some more AI full dumps
|
|
(AI500-AI599), which should be treated like the AI full dumps in the boxes.
|
|
|
|
Rack 6 contains HTJR dumps and old AI-KA personal tapes. The HTJR tapes
|
|
are candidates for re-use, though you should first try asking GSB whether
|
|
there is anything useful on them -- HTJR was being used for VMS NIL
|
|
development during this period. The AI tapes are too old to be re-usable.
|
|
|
|
Rack 7 contains dumps from RMS's Lispm file system, which can be re-used or
|
|
trashed as you please. There are also lots of personal and system tapes
|
|
there, most of which are labeled. For the ITS and Lispm board tapes, I
|
|
suggest that you have TK look at them before you decide to trash them --
|
|
they should not be re-used, they are too old. For the other random system
|
|
tapes, do what you please.
|
|
|
|
Racks 8 and 9 contain dumps from various Vaxen; you can probably figure out
|
|
better than I what do do with these. |
