If you do some wiring on the Qbus backplane, you can do 22-bit. Throw in an 11/93 CPU, SCSI and what else, and you'll have an awesome system in a VT100 body. This is probably a better idea, but it will likely need some beefing-up of the power supply. The power supply in a VT103 is a bit underpowered for bigger hardware. It can be done, though. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
