Tim, the SED indicates Seiko-Epson, now known as S-MOS.  The part
     number isn't on their standard products list or my '92/93 data book,
     it may be a custom.

I have just got an order from Greenweld of surplus.  Included are 20
dispalys.  Thet consist of some circuitry, an 8 figure 7 seg display and 3
leds.  On the bach there is one group of 4 pins, 2 of 2 pins and a lone pin.
The device is the Rohm 257D and the surface mount chip on the back is labeled:

SED5031Moa
F02  513
JAPAN

Any details of this device would be great - it looks like an excellent PIC
display to me!
