Custom PDSP-1881 32x4 LED Character Display

I have an unnatural attraction to vintage, rare, expensive, obsolete displays ... so naturally I decided to buy a bunch!

There's something special about nixies, numitrons, and vfds that warms my hearts but I also have a fondness for LED's as well. I've had my eye on the PDSP series of character LED modules but they usually sell for ridiculous prices in one off quantities. Well I finally found a seller who was selling lots of 10 pieces for a semi-reasonable price so I knew it was now or never ...

Enjoy this project?

I love vintage/rare/unique display technologies, just a shame that they are so expensive. I got lucky this time in finding a seller who listed lots of these displays for $40/ten pieces (instead of the usual $30 a piece), not exactly cheap but probably the cheapest I will ever find them until they become impossible to find. I could do so many interesting, complex projects if displays like these didn't tend to cost an arm and a leg.

It took me 30 years to get this display working again:

You're in the right place to share this attraction :D

I have a little work to do on the driver software to make it serially controllable and then I have to figure out what I want to display other than the obligatory clock I always end up making. Maybe I'll make it into some sort of wifi connected news ticker, or internet radio/plex interface display.
