Obscure z80 oil well logging computer

[Stonent]

Reading the thread on building a z80 computer makes me wish I still had a rack mount computer that my dad brought home one day.
The computer was called an LP912 (I can't find anything on it on the internet) and it was used for oil well logging.
It had inputs for camera and some kind of radiation sensor.  He brought 2 home and neither worked, but through a combination of swapping boards between the two I got one to power up.

I distinctly remember one or more Z80A processors and also a Z80 Dart. One of the chips I remember was a white ceramic package with a gold metal part in the middle. It had a variety of switches and LEDS on the front and a membrane keypad.  There was also a small CRT, about the size of one you'd get in an analog scope.

There was a text based menu and graphing functions which just displayed meaningless information because the required sensors were not attached.

And for me at the time, the most useful function, was +/-12V and +5 BNC jacks on the front.

I remember when selecting camera it would say something like "waiting for camera" and would pretty much be frozen until you power cycled it.

I found this article: http://www.theatlantic.com/technology/archive/2013/05/the-time-exxon-went-into-the-semiconductor-business-and-failed/275993/

Which makes me wonder if somehow the computer was designed by either Schlumberger or Exxon.  It did seem to have a high percentage of Zilog and Fairchild parts in it.

The boards went into a card slots and some had ribbon cables connecting them together.  I think it was around 1992 to 1994 time frame when I had these and I think they were built in the mid 1980s.

If anyone knows anything about this computer I'd be interested in hearing about it.
