My last DEC Field Service experience was with HSC-50's.
They had their own bus (no name known by field service).
I thought they went from F11 CPUs to J11 CPUs in the later ones (HSC70).

I wondered if they ever used 78032 (uVaxII chips) in some of them.


  d|i|g|i|t|a|l had it THEN.  Don't you wish you could still buy it now!
