Also in my junk box there is a 65802, a WDC chip. This was the 16 bit
version (like the 65816, also by WDC) but with an 8 bit data bus and 16 bit
address bus, that was a plug in compatable for the 6502. (actually, I am not
sure about the two above part numbers, but generally my memory does not fail me
on such things). Also, as I recall, it was a 4 MHz part. Are those parts still
availiable, or are they long gone like so many other good chips?
