Bought one of these for a couple $ today at my local parts depot. Has 14 pins on each side, and looks like a 3-1/2 or 4 digit display. Trying to figure out how I can test/make use of such a device. Any ideas are welcome. Google doesn't help much, at least not with what I have searched on so far.
Also picked up a 3-1/2 or four digit LCD display mounted in an aluminum case with a 22 pin ribbon cable coming out he back. Says PROTO and some numbers on the back. Similarly, any ideas on how to test/make use of such a device are welcome.
Fooling around while I try to finish constructing the circuit to which I hope to affix such a device.
