Here are a pushbutton switch assembly, numbered and blank button caps, a 15 position
lever switch assembly, the lower lighted bezel and a knob and dial from a display scope.
The bezel has a row of lamps inside to illuminate the desktop.
The two console pictures were taken at the Computer History Museum.
This assembly was part of the Duplex Maintenance Console, and was located over
the scope bay. The left switch would be labeled "Signal Test" and the right
"Spare", and have an Off (up) and On (down) position. The test jacks
are "Probe" (red), "Gnd" (black) and "Scope" (BNC). The assembly number is
3021351. The last two pictures are from the Computer History Museum.
This is a Charactron Deflection Yoke from the large 19" tube in the display
consoles. It has IBM part number 3016011, Serial number 140, and also has
labels Type Y17-25C, 822533 and 004-46. It was manufactured by Stromberg
Carlson for IBM. They also made the 19" Charactron display tubes.
This is a 5" Typotron display from a display
console. It has IBM part number 3016020, Serial number 900039, Type
6577. The tube is 31" long, 5-5/8" in diameter at the front face,
and 2-1/4" diameter through the neck. It was manufactured by Hughes
Aircraft for IBM. This DD (Digital Display) tube displayed only
character information, and was located in the upper right corner
of the console.
This is an almost complete DD Unit, with the shielding, coils and adjustments.
ID is IP-385/FSQ, IBM p/n is 3046227.
Various meters from the
power supply
cabinets. I can't say for sure that all of these were from a SAGE system, but the
part numbers are in the right range.
Capacitor tray from a Q7 power supply. The indicator on the front panel would be
a neon lamp, which illuminated when there was a shorted capacitor.
Light gun from a SAGE display console. Unfortunately, the guts of this one have
been mostly stripped out, but I do have the photomultiplier tube used in these.
IBM p/n is 3082118.
