[comp.lang.pascal] uVAX/ELN <-> KXJ11/MicroPower Pascal interface

anneser@pwa-b.UUCP (Dean Anneser) (08/05/87)

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).
                     
        host VAX/VMS                VAX/ELN system
        ------------                --------------
        KXJ task image ---------------       K   K
                                    /        X   X
                                   /-------> J   J
                                             1   1
                                             1   1 
                                            (1) (2)

  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.
