I got out my Tektronix DAS 9129 logic analyzer mainframe, which uses a
red/green/yellow beam penetration CRT. It uses raster scan, whereas
my other device with a beam penetration CRT, the HP 1338A (also
red/green/yellow) is a vector (X-Y) display.
I'm pleased to find that the 9129 passes self-test and the display
works. Unfortunately I do not have any logic analyzer acquisition or
pattern generator modules for it, so other than admiring the pretty
display, it's only useful as a boat anchor.
