Message-ID: <289@ssc-bee.UUCP> Date: Wed, 13-Feb-85 12:30:24 EST Article-I.D.: ssc-bee.289 Posted: Wed Feb 13 12:30:24 1985 Date-Received: Fri, 15-Feb-85 03:36:38 EST References: <372@aicchi.UUCP> Distribution: net Organization: Boeing Aerospace Co., Seattle, WA Lines: 19 Yes. A friend replaced the 6502 in his old ][+ with a 65c02 with no problems although some say it will not work. It may be a critical timing problem where some chips will work in some Apples but not others. caveat: Not all 65c02's are created equal. If you want to be Apple compatible, be sure to buy a chip made by the same manufacturer (NEC, I believe but check it out) that Apple uses. Different companies have added different instructions to the 6502 basic instruction set! Best bet may be to buy the chip from your Apple dealer. -- Mike Eve Boeing Aerospace, Seattle ...uw-beaver!ssc-vax!ssc-bee!eve
