Small Update:
I got the TN-VDP working in 40 and 80 columns and just today I figured out how to get the Vsync interrupts working on my eZ80 board.
The rev2 board will include some changes. Of course I have reversed the data bits, and I also added a diode to the INT pin to make it compatible with an open-collector type bus.I am very pleased with the speed so far. at 36 MHz, I can drive it with an IO cycle time of only 200ns, equating to 4.8 MHz
