Quite true! Rumor has it though that NEC *is* coming out with a Vxx chip that *will* emulate the Z-80 instruction-set. I dunno if NEC has made any public statements about this, but you might give 'em a call and talk to one of their application engineers, etc. /kim -- UUCP: {decvax,ucbvax,ihnp4}!decwrl!mips!kim DDD: 408-720-1700 x231 USPS: MIPS Computer Systems Inc, 930 E.
