Burroughs Panaplex display data needed

[Tom Jennings]

I recently acquired a virgin Burroughs Panaplex display, and
can't find data for it. It's a 24-line, 40-column display, tube
only. Character matrixes are 5w x 9h (!) so it'll do decenders.

The only markings are a simple "N-0008" on one edge. It's got
double staggered rows of pins on all four sides. The whole
thing is about 8" x 10".

I know how (on paper) to drive panaplex displays (it's nasty)
and would love to work up a nice display with this thing if I
can find pinout data. Any ideas?
