Williams ( and Data East) LCD display

The intention is to have something to test display output on the bench without the need for high voltage.

It is prepared to support also LED Modules with a HUB75 interface (not implemented yet)

All Williams System3 up to System11 and Data East (non DMD) gam,es are supported.

Software is still under development! Let me know if you facing errors.

Documentation

WillDisp is using an integrated (SMD) PIC device ( PIC18F67K40 ). The PIC can be programmed via the on board 'ICSP' connector and a 'Pickit3', have a look here: PICKIT3

Programming is straightforward: connect the Pickit3 to the ICSP connector and start the 'pickitminus' software. Pickitminus will detect the PIC type. Import the hex file provided and push 'program'.

-----------------------------------

Connect Power, Strobes, Display BCD and Display Data to the corresponding connectors on your MPU.

Instead of the power connector you can also use the 2-pin connector on the left and connect 5Volt there.

With the 'STEP' switch you can change display mode between:

System3, System7, System11-Numeric, System11-Alphanumeric and DIAG.

Willdisp will store the last mode set to the internal EEprom and start with this mode next time.
