UDA-50 help needed

[paul at msdc.UUCP]

Our local DEC office claims there is no information for purchase about
programming UDA-50 controllers. I'm going to try and use a dual-ported
RA-80 from two systems, simultaneously. Does anyone possess information
on how to accomplish this (or has someone already accomplished this)?
Our config: VAX 750's running 4.1BSD.
