I'p pretty suee I've seen a 6507, at least in a databook. And the 6509
was a Commodore-special with a built-in MMU sicruit used in the PET II
(P500 etc).
SOme of the cut-down ones turn up in old Commodore printers, BTW.
And there's the 6500 (yes, '00'). It's a 40 pin microcontroller, and
it was used eg. on Seagate ST-225 drives.
Yes, I've come across that one...
I have an old Rockwell databook which lists most of the varients with
pinouts and specs. Very handy...
