This (or some identical-appearing descendant) was my very first mode of contact with a computer. It's remarkably portable for 1969-vintage information technology, I'd say-- much lighter than an IBM Selectric typewriter, let alone a GE Terminet.
In the mid-seventies, my father would come home after a long day hacking the Honeywell mainframes at the office and hack some more after dinner with his Silent 700, through that 300 baud acoustic coupler (we got a second phone line for the purpose). I had no idea that every kid's dad didn't use a computer all the time. I was living ten or twenty years in the future and didn't know it. There were a few games on the system; it had Original Adventure, tic-tac-toe and Hunt the Wumpus.
Around 1977 or '78 we had a program of once-a-week enrichment courses in school, and I took one on BASIC programming in which we learned everything on paper, since we had no actual computers. At the end of the course, somebody wheeled in a Commodore PET 2001 on a cart and we took turns typing in our little programs and running them. I made a typo and got a syntax error, and then it was somebody else's turn. That evening, my dad dialed in with his terminal and let me run my program on the engineering Honeywells.
