I think a lot of people are just mistakenly taking 'Mostek' as a short form
of 'MOS Technology'.

I have a GTE 65SC02 here that has yet another variation of the extended
instructions

Here's a snippet I found:

<<In 1975, MOS Semiconductors introduced the 6502. It has been redesigned
and
   enhanced by Western Design Center (WDC) in 1981. It is unknown who
designed
   the 65SC02, an enhanced 65C02 that has been licensed by GTE. WDC
developed
   the 16-bit successor of the 65C02, which did not implement the additional
   instructions of the 65SC02. But the 65SC02 is the base of both the
HuC6280
   by NEC used in their video game console TG-16 (PC-Engine) and the 65CE02
   by Commodore MOS (CSG). Some instructions show that the designers of the
   65CE02 have also been influenced by the 65816. The preliminary
   "C64DX SYSTEM SPECIFICATION" [1] says that the 65CE02 contained "new
   instructions, including Rockwell [65C02] and GTE [65SC02] extensions".>>

I don't think "MOS Semiconductors" is right, though.
