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.

Dick, take a peek over at
http://www.f15sim.com/center_ins.jpg. Look at
the far right of the image. There is a cluster of
engine instruments.
The RPM, TEMP and FUEL FLOW indicators use 3, 4 and
5 digit odometer style
displays. They're packing them into a 2.00"
diameter instrument body. I
need to be able to do the same with 7 segment
displays because scratch
building those mechanical numeric readouts would
completely obliterate my
budget. As it is, they're $150 each _without_ the
displays.
tnx.

It might help
konwing what the application is,
since another copy of the same
device might be more easily found than a
replacement part.
