Tower O' Flakyness, Or: Something Old, Something New, Something Borrowed, Something Blue, and Something Broken.
I figured I should just stack 'em all up and see what they looked like.
Counterclockwise:
Top: Borrowed ca. 2000 500 MHz Tektronix TDS3054B (thanks, Mike!) perfectly fine but for one bad probe.
Middle: Blue ca. 1986 125 MHz LeCroy 9400, with one channel kaput (see previous photo). Also boots only half the time. Danged thing has a 68000 in it!
Bottom: Broken ca. 1999 300 MHz Iwatsu 8631. Dead because of a power supply that failed one week after I bought it as-is (grr).
Bottom right: New(ish)Agilent Genuine HP! 33120A 15 MHz arbitrary waveform generator, doing yeoman service here as a 1.234 kHz sinewave generator.
Above it: Old 1976 Fluke 1900A frequency counter. I used an identical one when I worked at Motorola in 1981.
Top right: Blue again, I guess. IBM X40, running a soundcard oscilloscope application, which inexplicably flatlined just before the shutter opened here.
