I'd imagine it has a quite sparse instruction set, but it has 32, 32 bit processors in it, running at about 50mhz each, using microwatts each. Properly harnessed & pipelined, I'd think it could be pretty speedy & its in a 48 or 64 pin dip package! I'd think the package would make it i/o bound, but I'm just guessing. >Regards, >Les H -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
