unknown round multi-character Panaplex
Jonathan F.
I want to share this display, because its awesome!
I picked up a very special panaplex on ebay. It has a Burroughs-Logo on the PCB so i guess it was made / sold by burroughs. Sadly all the prints on the PCB were not any useful to find something about this display.
I will try to figure all pins out and then create a driving circuit.
1.) It has two 3-digit 7-Segment panaplex on it, those are multiplexed because all cathodes are in common, anodes are different. It also has an up and down arrow by the digits.
2.) It has the words TO and FR. Whats really interesting here is, that the parts of the letters are controlled individually, so the O is basically a 4-segment display.
3.) It has 4 multiplexed bargraphs on it, they either start in the middle, or on the outside, or can be used both way (did not figured this out yet)
So...what could be the use of this display?
I guess the "TO/FR" could be TO and FROM ? The digits could be speed, weight, distance or something else?
I don't really have an idea what the bargraphs are for...direction... maybe position?..
Notice the red and gold connector on the pcb (no its not a potentiometer), it is a little locking connector (screwlock like bnc) with gold pins on it.
Any info would be great, but i don't have much hope...

A guess:
Could it be a ‘cross-hair’ visor or a part of a level?

Clearly, it was made in 1976. That's what the PCB date code 2276 and the white
stamp 7644 both say. It's a rather unique part, probably part of some
direcitonal system as you say. I'd imagine it to be a really expensive gizmo, as
microprocessors were very new back then. Which makes it interesting that it's so
small.
It looks like it would fit in an aircraft instrument panel, especially with the
notches in the corners of the square PC board, which would leave room for knobs.
In fact, that red thing looks like a rotary switch base.
Probably from a 1970s avionics display.

The airplane thing is a nice idea... I have no knowledge about planes but i think this:

can move up and down, as well as left and right... mayb they tried to make this?

That is a CDI, A course deviation indicator. Or a related HSI (horizontal
situation indicator). It is connected to the VOR radio. The anaog versions have
a needle that swings left or right to indicate if you are left or right of your
proper course. That's the big horizontal bar. The vertical bar is probably
used for an instrument landing system. It would indicate how far above or below
the glide path you are. The numbers I guess, indicate the the bearing (which
radial of the VOR you are on and/or which you want to be on).

Can you tell me the diameter of the display (not the sisze of the square print)?
Because it is so scarse, I think it’s rather military than civil.

The diameter of the glass is about 73mm / ~2.8 inch , there is something on the glass that looks like glue or silicone, the glass without the glue border is about 70mm/ ~2.75"

cutout, so this fits well.

Ah, I thought it was much smaller, more in the size of a wrist watch.
Thanks,
