A Commodore SuperPET in all its glory. These machines were meant for use by computer science students at the University of Waterloo in Ontario, Canada. |
The SuperPET was accompanied by two contemporary floppy drives, an 8050 (which wrote quad-density diskettes), and a 4040 (which is closer to the 1541 that most Commodore users are familiar with). |
Programming manuals for the SuperPET. I was fascinated by these, including the Guess statement in

This ancient catalog got a lot of attention as its pages were carefully turned over. |
Jason brought a US Robotics modem (vintage 1987) in an unopened box. |
The modem is ceremonially unboxed. Inside was a 5¼" floppy disk and a manual extolling the modem as "one of the most advanced data communication devices in the world". |
