Really?

I think you are thinking of the PC[67]300?  Aka the 3B1?

The Convergent machines of the day were 68K based, and had nothing to do 
with any of the WE chips.

I sold/maintained Convergent gear for a few years before being hired into 
a shop that was inflicted with 3B2 hardware. Believe me, I know the 
difference between the two.
