Since people are showing off their clocks... I managed to get a Datum / Bancomm bc632D display from eBay a while back and it's
pretty cool.

>From what I can tell, they took an off-the-shelf model from Beta Brite (Now I think owned by Adaptive) and put an extra board in
there with the BNC connections, and of course their own firmware. From what I can tell most of those signs are just meant for
scrolling text and don't have any time ability.

The bc632D can decode several different time formats (I have it hooked up to IRIG), it has a RTC so it can flywheel when no input or
if you manually input the date/time. The only quirk is it doesn't decode the year properly, but once you set it manually it will
maintain the correct year (unless you leave it unplugged for a long time and the onboard battery runs out). You have a variety of
display options, but it's not as customizable as one would hope. I have it showing the time, then every 30 it will show the date for
5 seconds. Text size is about 2-1/4" high.

I think I paid around $50 for the sign on eBay, but had to pay about another $40 for a proper power supply (required 7 VAC.. not
DC). Still for under $100 I think it's a deal.
