KMSquote: ZOG with 0.05 to 0.1 sec response time was faster than needed

Quotation

We have also had experience with response speeds at the very fast end of the scale--0.05 to 0.1 seconds. In 1978, as part of the ZOG effort at CMU, we built two special ZOG terminals using a high-speed vector graphics display, a touch screen, and a fast drum, attached to one of the DEC PDP-11 processors in the experimental multiprocessor called C.mmp. We were not able to study the use of this system in any detail, because it had no editor available, it was difficult to download material from our main working environment on a PDP-10, and the hardware was unreliable. But we did satisfy ourselves that we had bounded the optimal response time from below.   Google-1   Google-2
