Yup, those were my doing. I believe I still have several more hiding in
old boxes, which will probably hit the free parts box someday.
There were actually 2 different designs for that PCB, one with 4
displays, the other with 5. Neither has a schematic. They have very
different wiring. As I recall, the 4-display one was meant to run on 5
volts, and the 5-display one used 3.3V power.

IIRC, These were Paul's. I'm pretty sure they're just 595s in series.
I have mine out in my car right now. I'd be interested in working it
out as well.

Hey there, dorks,
At one of the previous meetings, I picked up an array of five
seven-segment displays (each three-digit with decimal dots between
each digit, a separator colon between digits 1 and 2, and an
indicator dot on the top between digits 2 and 3, part number
LTC-4624JR) driven by five 74VHC595 shift registers.
It looks like custom work, and I was wondering if the person who
built them would happen to have the circuit diagram for me to look
at. I'm considering building this into a project instead of
setting up my own, and I'd rather not fry it in a hurry.
The board is plain, and definitely not group order. I'll attach a
picture of the module below.
Any help is good help, but I suppose I could probably suss out the
circuit myself if noone knows.
Thanks!
