 Ash trays??  HA, they had auto-style CIGARETTE
LIGHTERS
 BUILT INTO the "radar screen" consoles!  Take a look at a
 photo!

 The IBM 803 proof machine developed in the late 40s had an
 ash tray built in, it was the only IBM machine I ever saw
 that had one.    I stood right in front of the scopes at a
 SAGE site but I don't recall the ash trays or lighters.
 But I do remember the light guns, blue lighting and the
 aful flash of the high persistance scope when they whrere
 drawn.

next to the ashtray, there's a little round hole with a
chrome ring - that's where a standard car cigarette lighter
plugged in.  A 6 V lighter would work fine off the massive
filament transformers these things had.
