Yes, of course I remember!  The beer was good :-)
Unfortunately I could never get the UC07 passing init step 4; setting up 
DMA for descriptors... :-/

Anyway, since this is a CVAX it should be simple to get a kernel that at 
least says hello.
You need to add the boardtype to include/sid.h (seems like you have the 
info already) and then
have it correctly added in the switch table in vax/findcpu.c.

Is it using MTPR for console communications?  Then add it besides the 
650 board type, otherwise
you must find out how it communicates with the console.
