I remember that TI luggable - that sucker weighed a ton! I dragged it from the lab to my dorm a few times to log in remotely, but carrying it on a bicycle was a dicey deal and I got over the novelty pretty quickly. I'd forgotten who made it until you mentioned it - good memories!

Tymshare provided me with a Teletype ASR-33 (with the built in tape punch and reader). I had an AJ 300 baud acoustic coupler. We had a second phone line installed, 'cause my dad was tired of picking up the phone and hearing tones. I ended up rewiring the house phones so I could put the terminal in my room. When I went to the Pentagon in '79 I was in charge of PENT-TIP and got to take home and travel with a TI Silent700 with a built in acoustic coupler. We had a bank of 300/1200 baud modems on PENT-TIP. Our IMP was connected to the Arpanet via a 56K modem that was the size of 5 foot tall 19" rack! Back in those days it seems TIP phone numbers were closely guarded treasure. I still remember when I got an LS ADM-3A (no more finding rolls of thermal paper). I still have it, though I don't know why... Geoff On 2/17/20 11:20 AM, Anne P.

A friend dropped by the lab I worked in at Harvard and wondered if I had an MIT ITS account and I said no wasn't even sure what it was other than a time sharing system at MIT. So we had a modem and dumb terminal and dialed-in and one could create an account from the login prompt which I guess today seems mundane but really was totally unintuitive, getting logins on time shared systems generally required paper work and proof one should have access. And I became BARRYS@MIT-AI (no stinkin' dots back then.) He showed me some ARPAnet things and I was suitably amazed and explored more from home where I had my own dumb tty and modem. TBH I didn't really have much use for it at the time other than joining mailing lists or similar. Occasionally if someone was in the room I'd say "watch this!" and get to a login prompt at Stanford or UCL (London.) They were usually impressed. I did use the local area network to access MIT-MC to use MacSyma (a symbolic math package) which I did use in my work. I was fairly amazed that my files were visible on either machine. etc etc etc. -- Gene LeDuc | A ship in port is safe, but that's not Technology Security| what ships are built for.

There is probably a "law" enshrined somewhere: Bandwidth is like closet space, demand will always manage to exceed capacity. Gene On 1/24/20 6:52 AM, Aaron Gould wrote: Thanks Hugo, very interesting.
