Hmn, the name doesn't ring a bell.  I was working at Harris
Semiconductor at the time and spent about a year working on the
processor data chip implementation.  I only dealt with a handful of the
DEC engineers.

Oh, it's only been 23 years or so ...

Most of the revisions that we did on the data chip were to get the speed
up to an acceptable level, though we did run into some data integrity
problems.  I don't know anything about the microcode history.

The only non-wetware info I have from that time is a preliminary copy of
the "DCJ11 Microprocessor User's Guide".
