And the VT240 was very slow. I never saw or used a VT125, so I don't know > how it compared, but it didn't have color, right?
It did have color. You could connect an external RGB sync on green monitor to the BNC connectors at the back of the VT125. For output on the built in black/white display it generated a grayscale signal that was mearly overlayed on top of a the VT100 signal. This also meant that on the RGB connectors you only had the VT125 graphics. No VT100 output. The VT125 coprocessor used an 8085 processor. Somehow it intercepted the serial line passsing through that strange white connector on the VT100 board and processed the ReGIS commands. VAXstation was definitely cool, but the price tag compared to a GIGI would > have been ridiculous, I suspect. /Mattis
