Signetics makes a 68000-based part named the 68070. I believe it is targetted at embedded-controller applications. It has a number of nifty features that seem designed to minimize the number of "glue" chips wrapped around the processor in a typical controller application (e.g.: if I recall correctly, there are a pair of UARTs on the chip). I agree that it's an unfortunate name, though Motorola has at least two future generations of the 680x0 family before the name becomes an issue. And I rather doubt there will ever be a 68060 (an '050 is likely though). The issue isn't so much technical as marketeer-ical. If it ain't pronounced "RISC", the market don't wanna know about it no more... (Anyone from Motorola who knows better is welcome to correct my guesses. ;-) -- >>"Aaiiyeeee!
