Talk:Technology Square

9th floor map

Noel, we're interested in hearing your comments about the floor plan. Larsbrinkhoff (talk) And you already gave some, thanks!

I wasn't there during the CTSS/Multics era, but later on there was still a huge I-beam running along the floor where '1401/DM PDP-6' is on this map, and I was told that that had been installed to hold the Multics (or CTSS, I forget which) tape drives (or maybe drum). So it may have been all through that end. It shouldn't be hard to find out.

Also, LISP machines were scattered all over the floor; the prototype CADR, along with the CONS machine and the chess machine (CHEOPS) was in one of 904-906 (I forget which); others were down near AI. Jnc (talk) 22:01, 25 January 2018 (CET)

Where did the four KS10 machines go? Larsbrinkhoff (talk)

Where the ML KA used to be.

Speaking of the KS10's, I wish I could find a copy of the letter I wrote for Dave Clark to sign, asking for the donation from DEC. I looked on the MIT-CSR machine (whose filesystem I recently recovered), but alas, not there. It must have been on one of the other machines (XX, or one of the ITS's).

I see various references in mailing list archives, but not specifially that letter. I believe there were two rounds of deliveries? First one KS10 replacement for AI in 1984, and then three more in 1985; does that seem right?

"I have organised a campaign to get DEC to give MIT several more of the little critters. A letter was written asking for a donation of several of the machines to MIT (i.e. both LCS and AI); due to the time pressures involved (all of the remaining unsold KS's were about to be scrapped) I couldn't get a lot of big wheels to sign, but Dave Clark did agree to sign the letter and lend his name to the campaign."
