Not planning on selling them (but once I have it finished, I might negotiate with someone else to sell them) but if you want the display with serial input it's part number GW128x32C-K610A from www.itron.com.

I ordered from the UK guys (who actually designed the PCB & micro that the glass sits on) and they take credit cards; the displays are £69.57 each, plus VAT.

I (very carefully) removed the display from the PCB and attached it via a short ribbon cable, as there wasn't room for the PCB inside the revcounter at the preferred location - this will obviously void any warranty on the display if you do it with yours!

Remember the serial is at TTL levels, so you'll need both a 5v PSU and a MAX232 level shifter to hook it to the empeg serial.
