Got the RX01's running and TSX

I have run TSX+ since the early 80's.    I developed a few handlers to 
do graphics on a Peritek VRG-Q  and also for data acquisition.

Nothing like like an  J-11, 4Mb and a hard disk to make a excellent 
personal workstation back then.   RXV21's were not a problem as TSX+ 
(>v6 I think) could automatically low buffer for them as required.
