So far it looks standard. Never run the display without applying BP 
pulses with 50% duty cycle.

I once wrote a simple test program for a G648D (?) display that sounds 
similar to what yo have. The program was a Turbo C one under DOS and 
drove the display through a parallel port (bit banged). If you want it 
email me privately please (me toos privately too please).
