Not necessarily.


I personally retrieved a complete copy of the MIT-CSR machine; it has
people's personal stuff mixed in with public stuff, and I'm too lazy to
curate it to get rid of all that - and retrieve the public stuff that's in
people's personal directories, that they just left there, instead of
installing it, because they were lazy.

I have occasionally posted stuff from it:

  https://gunkies.org/wiki/User:Jnc/Online

maybe 5% of it - and can retrieve anything there is a particular call for. (I
suppose I should post a list of _all_ the files on the machine - I've got a
'tar -vt' output in a file that would do it.)


The story of the DSSR/RTS machine, the biggest/oldest of the MIT UNIX
machines, is probably not good. It had a tape drive, and was regularly backed
up onto magtapes. (I remember a big rack of tapes in their machine room on
the 5th floor - the same floor as CSR.)

But - they may have been discarded. A couple of years back I asked Prof. Ward
(head of the group) what happened to the tapes, because I was looking for
something (the source for the Algol interpreter, IIRC). He didn't know what
happened to them. Maybe the MIT Archives got them? (Most of them would be V6
dump backups - I'm not sure V7 was ever installed on the machine.)

The semi-good news is that a lot of the stuff was duplicated on the CSR
machine - you can see some of it listed in the list above.
