CC545As do not need controllers, if connected to the

channel on the Cyber. Maybe the earlier Cyber consoles did, but not
the late type that Richard has. The early single tube Cyber consoles,
between the dual tube type of the 6600 era and the CC545A, were
crammed with 3000 series logic boards, rather than the few larger
boards of later types. The last, for the Cyber 990, was single tube
and color, but I do not know if it was vector.
Not according to the CC545 hardware manual (62952600) that Richard
pointed to:
"This manual documents the CONTROL DATA CYBER 170 Display Station,
equipments CC545-C/D and the U.L.-listed equipments CC545E/F. The
display station contains a 21-inch crt to display information
received from a computer via a CYBER 170 Display Controller..."
Nothng I see in the schematics for the thing shows anything about a
display controller, just the basic display box. The display
controller interprets the 12-bit data sequences and outputs either
character or graphics (depending on the content), automatically
keeping track of the drawing position.
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.
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.
