A couple of PDP-8s to keep going as well as a Data General of the same size. We doubled the memory on that, added another 16KB and bolted it to the wall with a cable going to the cabinet.
The PDP-8 was first introduced in 1965.

"Data General was one of the first minicomputer firms of the late 1960s. Their first product, 1969's Data General Nova, was a 16-bit minicomputer intended to both outperform and cost less than the equivalent from DEC, the 12-bit PDP-8."
The PDP-8s were on a Mass Spectrometer and an Xray Diffractometer and the Data General on an ESR.
To get a PDP-8 going you put in near a dozen binary instructions on the front panel switches and then it could read paper tape. Then another tape with the specific programme for that job.
The switches, 3 to a number i.e. a 7 would be all 3 switches ON. a 1 would be one switch ON. As each number was made up of 4 digits that meant 12 switches.
