[OT] Need 7 segment displays...

I've used the little 7x5 dot LED displays from BGMicro
in my 8080 single board computers. They look great and
are daylight-readable. Problem is, that they are
almost completely stupid, come 4 in a 12-pin DIP
package, and require transistor drivers. The good
news, is that even lowly PIC's can be programmed to
drive them, which I've done for a few projects. I have
RS-232 going into the PIC at 1200 baud with a few
rudimentary "cusror" displays. Also, good news is that
they are of super quality (ceramic/glass), cost less
than $1 each (not nearly what they cost originally)
and I believe that they might be classified as
"daylight-readable". I think I have the code for a
16C84 around here somewhere. They also have much
smarter, but also larger, red and green displays.
