  Perhaps I'm confused.  I may have been told
"Synertek" by someone at
 work, c. 1984, and they might have meant Signetics.  I _do_ have some
 68000 chips with a "block S" logo... would that be Signetics, then? 
Sounds like Signetics.

Those are still relatively uncommon.  Motorola parts are obviously
the most common, perhaps followed by Rockwell and Hitachi.

Anyone know whether Hitachi ever shipped their HD63000?  That was to be
a CMOS version of the 68000 that would have predated the Motorola  MC68HC000.
...

I heard somewhere that Mostek alone of the second sources had a license
to make the 68020, but I don't think they ever did.

Hi
 Toshiba did a 68301 varient of the 68000 that I know of.
( it is in my telescope control ).
