Care to elaborate? I've read the programmers docs for the 700 and 710, and they look like really hot chips. Particularily the reduction in # of interrupts to be serviced by the CPU (in a multitasking environment) would seem to be a large win. The 710's indexing registers mean you don't have to essentially use a code-generator to queue up operations. Note: I work in a 680x0 multitasking environment, since from your comments above that's likely to affect your comparison. -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.commodore.com BIX: rjesup Disclaimer: Nothing I say is anything other than my personal opinion.
