I found this at Active Surplus today for $1.50. It has eleven LA-301VL (7-segment common cathode displays) on a 2-layer pcb.
Numbering the pins and digits from left to right, here's how the pins correspond to digits:
Digit | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
Pin | 1 | 2 | 3 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 |
With respect to the segments, here's the relationship between the segments and the pins on the PCB:

I'll need to build a multiplexer to control the display. This should be interesting.
Thanks man, just got this from active myself.
