I have a MicroVAXII with a KMV1A. Are you refering to such a card with
the "LSI-11 on the Vax"? Does this mean there is a V7 running on it?
I really don't know much about that card. Might have been used for I/O with
an IBM 3090 in this computer.
Clem is referring to the VAX-11/780 (and its follow-ons the 782 and
785), which used a LSI-11 processor (PDP-11/03) to load its microcode
on power-on. IIRC the LSI-11 front end also ran the system console
device (originally a LA-36 DECwriter terminal).
The third generation PDP-10 CPU (the KL10) similarly had a PDP-11/40
front end that did the bootstrap loading and also acted as a
peripheral device controller.
