The 65816 was also co_manufactured by GTE and a number of other semiconductor companies during the mid-late '80's.

A 6502 pin compatible version of the 65816 was also produced by WDC called the 65802 (also: 65C802) which had restricted memory addressing due to pin compatibility limits, but was otherwise identical.
