That's the one I had.  The CPU board and the backplane were the same as 
in the DEC units and everything else was designed by Heath, including 
the optional paper tape reader/punch.  Eventually I installed 8 inch 
floppy drives.  It ran RT-11.

RT-11 Ahhh, Remember how every odd numbered release was better than
every even numbered one! (can't recall the detail). I 'ad an AR11
board in a pdp 11/10 (1) once - it was great fun. Wrote assember
interfaces to FORTRAN to drive it more easily.

Same with VMS - the even point releases added stuff, and the odd ones 
fixed the new bugs. The last point release of each major number was 
usually really good and stable - 3.7, 4.7 and so on.

The Harris chip from memory was a PDP-8 architecture.

Then DEC made their own chips in their own foundry, leading to the 
Alpha.

Having messed around with LSI-11, T11, J11 not quite microVax in my days 
there.
