.. very close. Apparently there was a process
difference.
By 1980 intel was shifting to mos/Hmos/HmosII and by then those
parts were way down the the process scaling and 32xx were nearly
extinct. In 76, that was not the case. Keep in mind my comment that
intel did morph parts into one another.

Though intel did at times morph one part/process
into another.
According to the 1980 Component Data Catalog, the specifications for
the 3205 (p. 2-22) and 8205 (p. 6-45) are identical. DC, AC, and all
the graphs.

You're right about the PMOS=> NMOS=>HMOS=>CMOS shifts in technology, but
I'd be surprised to learn that the 3000 series parts as well as the 82xx
bipolar parts weren't manufactured by NS, MMI, or TI.

Exactly. Intel had bipolar fab but limited capability. Actually you
forgot Signetics and likely others that were used as silicon foundaries.
This is something that has always been commonplace in the industry.
However no one ever supplied the 3000 two bit slice other than intel.

I don't think this was an accident, nor was it a mistake. The only
reference I've ever heard/read made to a bipolar fab under Intel's ownership
has been from you. It's not unlikely that I could have missed it, being
relatively uninterested in issues like who owned the fab, but I have looked
inside a number (50 > n >150) Intel bipolar parts among others' bipolars,
and never have I seen one without another manufacturer's logo. MMI was
pretty common among them. This was done in order to "decode" IBM, HP,
Burroughs, and others' stock numbered parts when I happened on a significant
quantity.
