Rhino,

Thanks for the info. I have got a different 4X40 (DisplayTech LTd closing down sale for $5, how's that for a bargain) and - IT ALL WORKS OK - along with the code/circuits for driving two ENABLE pins.

I would still like to track down the pin-out for the Futurlec JHD404A1 if anyone out there has the info.

Regards Bill Legge
