I’ve kept the 5.25 disks (3!) for the FORTRAN Star Trek game used late at night on the company Digital-PDP 1100 in 1981.
They have probably succumbed to redox-erosion by now but...history fades slowly from the mind.
I guarantee you, not 1% of the posters know what a Digital PDP 1100 is, especially from 1981......I started with Burroughs in 1981 supported the B1000 and later A-series Mainframes, carried a 65mb disk pack around in my car with all the software I need to support someone, if I need anything else I had Mag tapes....Digital aka DEC as I knew it and Burroughs along with a whole bunch of others don’t exist anymore...
