It ran on the 7094. In fact, as I recall the transition IBM made from the 7090->7094 was the result of MIT-suggested improvements *specifically* to make the machine time sharable. [we did a similar thing here at bbn at around the same time: in our case we were working with DEC and specified the upgrade from the PDP-1c to the PDP-1d. CTSS was *not* compatible with us... :-)] /Bernie\ Bernie Cosell Internet: cosell@bbn.com Bolt, Beranek & Newman, Inc USENET: bbn.com!cosell Cambridge, MA 02238 Telco: (617) 497-3503
