I have a couple of computers that use them (video games actually) and would like to know the chip's instruction set. The 6808 is a 6802 without the 6802's internal RAM. The 6802 is a 6800 with a small internal RAM, and most important, an internal clock circuit. There are no instruction set differences between the 6800, 6802, and 6808. Of course, double check that indeed you've got the 6808 and no the 68008, which is a 68000 with an 8-bit external bus. Can anyone point me towards book that describes its operation? Look for any of the old 6800 books.
