Would you like to help bitsavers?
We're looking for documentation and software for
minicomputers and mainframes, from the 50's to the 80's.

Help Us Save What Bits Still Exist

Work on the bitsavers project has been going on now for over
five years, and it is appears that very little software for
minicomputers and mainframes has survived in machine-readable
form from the mid-seventies and earlier. If you know of surviving
software on 1/2" tape, paper tape, cards, DECtape, etc. from
users groups or computer manufacturers, please contact us. Equipment
is available to recover these bits, and in some cases can be brought
on-site.

There is still a LOT of organizing to be done here!
Very few of the paper tape images have been verified, for example.
