[SIGCIS-Members] Looking for earliest mainframe contracts and computer contracts archive

Dear SIGCIS members I was wondering if someone has any mainframe and/or supercomputer contracts? or if there is an archive of computer contracts? jurisdictions and time periods, no bar although the older the better. The query is fairly broad so time share, leases, procurement contracts across contexts are very welcome :) I wish to look at the evolution of vendor restrictions (if any, although i think there would be ?) Happy to e-meet you all! Regards Anushka PhD Candidate, Institute for Information Law University of Amsterdam Sent with [Proton Mail](https://proton.me/mail/home) secure email.
