Seriously, your H8 can COMPLEMENT a register faster than a 68000? My manual says that the 68000 can complement an 8-bit or 16-bit register in 4 cycles; a 32-bit register in 6 cycles. Even on an 8 MHz 68000 (and SUN is shipping 10 MHz boards) this is 500 ns for 8- or 16-bits and 750 ns for 32-bits. I am assuming that the H8 is an 8080; can it really complement a register (or do any instruction) in less than 500 ns? Note that I am not claiming that the original comparison is valid, nor that yours is; I am just wondering about your claim, since I don't know much about H8s or 8080s.
