When we turned off the last ITS machines at MIT (the AI and MC KS10s), we made their final full dumps available for download via FTP for a couple of years. We turned that service off when someone pointed out to us that in addition to keeping some important history available, we were also making a lot of people's personal projects and private mail files available!
Recently, the availability of several emulators for the PDP-10 has lead to a revival of interest in ITS. Thus, we have prepared subsets of those final file systems that we believe are free of all private information. (We also removed anything we thought still had a chance of being an intellectual property issue.)
If you find anything here that you think shouldn't be made freely available, please let me know.
Two file systems are available from the ITS archive FTP server:
Most people are probably only interested in the AI file system. AI was the machine where all ITS development took place, so its file system contained everything needed to build and maintain working ITS systems.
To save you time finding what you're looking for, there is a complete listing of the AI file system. (This listing does not include symbolic links.)
This is not the historic MC KL10 where Macsyma was developed and made available. This is the MC KS10 that was used almost exclusively as a mail hub. Pretty much the only stuff here that isn't also in the AI file system is a bunch of electronic mail archives!
There is also a complete listing of the MC file system.
Unfortunately we can't promise that everything is still here. Disks were small in those days, so things were often forced out to backup tape. Occasionally that might include the source for a program that hadn't been built in a while. Please let me know about anything that seems to be missing.
Currently missing from this archive is the INQUIR directory. Unfortunately the INQUIR database contains a lot of personal information - phone numbers, addresses, etc. - much of which is probably still correct. We're still trying to figure out how to release a "clean" INQUIR.
