Just thought I'd better follow-up on my quest for a working HP
logic analyser.  I had a 1630D with a PSU fault and a 1630G that
had been dropped (front panel smashed, CRT OK but connections
ripped off).  I found that I could swap the whole card cage,
power supply, rear panel and fan from the "G" into the chassis
of the "D".  Just a couple of ribbon cables (keypad and video)
to connect up.  The "G" boards had survived the impact unscathed
(no real surprise for old HP kit) and passed self-test fine.

BTW, the CPU in the "G" model has its original part number
(the "D" was HP house-coded) and it's a 68B09.  So, now
I have a working 1630G, and a full set of pods.

Thanks to everyone who offered manuals, too.  I'll be needing
the "G" manual now, and it looks like it'll be on bitsavers.org
soon.
