Hello, all:
While rummaging thought my stock of Commodore chips, I came across a
bunck of R6765 chips. I looked in some of my notes and I have "floppy
controller" written down and elsewhere "D765". Is this a Rockwell-badged
version of the NEC controller? Which Commodore drives was this chip used in?

Yes. I have no idea whether it is a licensed copy or a clone, though.
Which Commodore drives was this chip used
in?
Not necessarily in any -- Rockwell made chips for a heck of a lot more
stuff than Commodore computers. If it was used in a Commodore drive,
it would most likely have been the 1571 or 1581, since AFAIK those
are the only drives they made that supported industry-standard MFM.

Jep. Its a Rockwell made D765.
Which Commodore drives was this chip used in?
No, at least none I know of. Commo used WD177x Controllers
for their non GCR Drives. And for the early PCs, generic 765s
have been used. Also Rockwell did add the chip quite late,
to late for any Commo Products.
