> 4 + 2 chips

Can you give me the chip numbers ?

The 14 pin pin-out is easy, it's pretty much standard for most graphics
displays, it's the timing details that are killing.

Power is usually +5V and -28V. If the FEL power is on board the power may
be generated locally.

If at least one of the chips is a RAM or a SED controller, you may have
paralell access buffered display. Anything else and you have to bit-bang
graphics into it at display refresh speed. Mine is of the second kind.

The C program I have hacked up is just a test program that lights up a
frame around my display when hooked up to the parallel port.

I'll make a package with my interface schematic and send it this week.
