So the display controller is apparently separate from
this thing,
just as it is with the DD60. ?Where it's located, I don't know--the
CYBER 170 was after I moved on within CDC.
In the later Cybers (180s), it is located in the mainframe. Maybe in
the 170s there is a separate box.
Looking at the schematics, the power supply takes both
60 Hz single-
phase and 3-phase 208V 400Hz. ?The 60 Hz looks to be mostly for fan
power. ?The 400Hz is a regular delta-wye transformer feed with
several secondaries.
But if those transformers are also rated for 60/400 Hz service, the
console can be tricked.
