Nice!

I have seen the Q805 (Borris70 i think) but am confused how to sort this one in the library? Why 74 MHz? Or does 74 mean something else? My initial thougt was that it was because of an ES, but now i see what should be the production version.

The HD is a clock doubled i960
The HD74 takes a 37MHz clock

I know these processors are real, but it doesn't make much sense - why would Intel release HD74 chip if they had HD80? The only explanation in my opinion is that HD74 was released before HD80, and discontinued as soon as Intel came up with HD80.

Hm, my versions are 80960CF33,
HD50 and HD66.
I don't see HD66 in Gennadiy's list so maybe this phenomenon of doubleclocking was used more often.
