Jon The EE department had an 8S which I wish I could have gotten my hands on (UMR). I had both it and an 8I in the lab in the Materials Research Center building and ran a number of programs on both which matched, great run. The 1949 rack under the 8S backplane is a tty controller, clock and power supply with attendant hoses to the backplane above. I think that may be what you were asking about. I don't know much 8s history, but unlike the 8L and 8I which came with the backplane wired with a spot for the TTY, this may have been what you had to do to get a TTY attached. Or it may be an extra second device. Perhaps someone with more familiarity with the 8S backplane and options might know. thanks Jim

Jon 8s was 20 microsecond cycle time compared toclassic 8 at 1.5 microsecond? ( pulling from ancient memories in my head... correct em if wrong...)
