HP 1630 logic analysers

I'm trying to find out more about HP 1630D and 1630G logic analysers.
They're mid-eighties machines with built-in CRT and enough inputs
to debug a typical 8 or 16-bit MPU.

Now, does anyone have an operating and/or service manual for them?
Because I have a non-working 1630D, which I'd like to fix. There
are four LEDs on the power supply board labelled POK, OV, TH and PL.
POK must be power OK, OV is overvoltage, TH probably represents a
thermal problem, but PL has got me stumped. What does it mean?
Naturally, when the PSU fails (after a few seconds of switching on)
it lights up the PL LED!

I wonder how much compatibility there is between the 1630A, D and G
models (in terms of boards)? Do they share the same basic boards,
but with more input boards in the bigger (D and G) models?
