The original 6800 had an external clock which required a clock chip and a crystal. About 10 years ago, they came out with the 6802 and 6808 which have an internal clock and just require the external crystal. They largely discontinued the 6800 at that time. One of the two chips (6802 or 6808) has internal ram also but I don't remember which is which. -- ------------------------------------------ Email: chinet!larry@gargoyle.uchicago.edu
