Speaking of CDC 6x00/Cyber 70-series consoles...
I had a bit of a scary but memorable experience of sitting at the console of a
Cyber 73, many years ago.
My job as a systems operator basically involved watching the console for
magtape mount/dismount requests, printer service requests (e.g.,

Using all of those gates to do brute-force logic for character vector
generation is pretty brilliant. Edison was truly a genius because he
invented and sold the electric light so that people could stay up late at
night to listen to his phonograph invention that he also sold. The

Hi all --
I finally tracked down the EIS option for my 11/40 and I have it up and
running nicely (Ultrix-11 ATM, but I'll be playing with other stuff).
Right now I only have a 4-slot DD11 backplane for SPC/MUD boards and I'd
like a bit more space for expansion.
I have a few DD11-DK backplanes

UHF, yes, but not those. The final state uses 3CX100A5 UHF
One of the more interesting things about the DD60 display was the use of
2C43 "Lighthouse" UHF triode tubes to drive the CRT electrostatic
deflection.
Only being around briefly for the 170 system, I don't know how the
magnetic deflection was driven there.
I imagine that the cost of the DD60 was

Eric,
forwarded to the folks at Johns Hopkins with the need, thank you very
much!
They designed the board so they are likely to know what the part needs
to do, and you are correct it’s for ground support, so presumably they will be
able to design a replacement if necessary.
