I took PL1 after we got the Honeywell and had a grad assistant for good amount of classes. He took me up to the lab which had a room full of various manufacturer personal computers that were sent to the university to see how they worked and identify any issues. Some were the size of a four drawer file cabinet. That was the first time I saw a touch screen monitor which used a pen to make contact with the glass for a lunar lander simulation game. I have to say I had big eyes for all the "new age" stuff in that room.
Also remember playing what I think was the first version of Zork on the "games" portion of the system.
