Collection · since 1997
Minicomputers and Mainframes
Software and records from the machines that ran universities, governments and industry.
Payroll systems, scientific codes, operating systems and the in-house software of institutions that ran on minicomputers, workstations and mainframes, mostly recovered from reel and cartridge tape.
Many of these systems were the only record of how an organization actually worked. Some are still the only record of the data they held.
