Has anyone out there written a driver and load utility under VAX/ELN for a
uVAX-II to interface with DEC's KXT11-CA or KXJ11-CA peripheral processors,
which will:
1) allow for a MicroPower/Pascal generated runnable image for the peri-
pheral to be downloaded from the VAX/ELN host system "through" the
ELN system, to the KXJ's physically plugged into the ELN system (this
would be sort of similar to the KUI utility running under RT-11 on
PDP-11's).

2) allow for reads/writes between the ELN application on the VAX and
a MicroPower Pascal application on the KXJ11 via the dual ported
memory on the KXJ11.
This appears to be a hole in DEC's real-time strategy. They have targeted
ELN as being their real-time system for the VAX's, and peripheral processors
(KXT11-CA's and KXJ11-CA's) for the real-time market with PDP-11's, however,
have yet to provide a software interface for peripheral processors plugged
into a QBus uVAX running an ELN application.
Any assistance would be greatly appreciated. Thanks in advance.
