I have a couple of ancient modules on the shelf here - they are the
size of an old 3.5 digit DVM module with 4 MAN71 7-segment displays -
I have figured out that the main chip is a Mostek MK5002
counter/display driver, but I can't find any data sheets on Google
(just auctions for the chip). I'm guessing that it might have been
used in some sort of pinball or arcade machine because of some of the
hits I've gotten, but I'd just like to be able to reverse-engineer the
pinout of the edge connector on this module.
Thanks for any pointers,

My mistake... 4 x MAN72A seven-segment plus 1 MAN73A "+1" display...
so 0000 to 10000...

For the record, the module is an NLS 39-324 - it has the 4.5 digits
on the front, the MK5002N, three 4049 hex inverters, and a fist-full
of discretes. I'm thinking it's either a DVM module or a counter
module.

Ethan,
The datasheet at your link gives me an error. Did it work okay for you ?
Attached is a "clean" PDF with no errors. ( Actually I sent it to you
offline ).
Best regards, Steven Canning

Yes. I just checked it again and it was fine. You end up with a bogus
filename (Acrobat6_required.pdf or something like that) and an annoying
coverpage, but the data is all there.

Thanks for that.
