Or so the story goes. I don't think Nelson munged -> the screwdriver, though. On the contrary. Bill Bennett was fond of telling anyone around that "Tools don't just get used up." Nelson was rewiring one of the light switches, which, regretably, was live. He shorted the live wire to the box, blew the breaker, and arc-welded this 1/4" circular hole out of the corner of the screwdriver blade. He left it on Bennett's desk with a note that said "used up." Someone asked how many ITS machines there were. There was the original PDP-6, AI, and a KA-10 (with pager) (also called AI). There was a Mathlab KA, ML, with SC pager. There was a dynamic modelling KA, DM (home of Zork), also with SC pager. There was a new Mathlab KL (MC). There was a pair of KS-10's later which were renamed AI and MC. I think that was it for the systems at MIT. I think a few others were brought up other places -- one of the KL's went to Sweden, and I think MRC brought ITS up a few times on his machine. KLH has run ITS on his simulator.

I helped debug the RM03 code; there was a loop waiting for a controller status register to get lit that happened with RP06s, but never on RM03s. Unfortunately, ITS on an RM03 was pretty much useless; with only 67MB to play around with you ending up having to be fairly aggressive in flushing stuff. It was easy to flush some of the random crud that had accumulated over the years, but then you had to start making tough decisions... I thought about writing RM05 support, but I never got A Round Tuit. ;-) What did strike me was how dependent ITS had become on the network. There were links to MC: in the system directories, MAIL and INQUIR wouldn't run without the network, and I think that LISP would valret if it couldn't find the net. I still have the ITS pack mounted on one of the RM03 spindles, so ITS is only a boot switch away... -- Mark -- DoD #0105, R90/6 pilot, FAX: (206) 685-4045 ICBM: N 47 39'35" W 122 18'39" Science does not emerge from voting, party politics, or public debate.
