( LINE EATER) I was tinkering with a commodore +4 that I had bought at aa garage sale blew out the serial port. I traced the lines to a chip marked 8551 (or what looked like 8551). No where in the civilized could I find a chip that fit that description . I suspect the chip may be identical to the 6551, but wanted to make sure before i put one in and really fried the computer. Does anybody out there know anything that might help me??? Thanks, kenneke@jacobs.cs.orst.edu

Nicest feature of the PLUS/4 is this real ACIA. > Thanks, > kenneke@jacobs.cs.orst.edu -- Dave Haynie "The 32 Bit Guy" Commodore-Amiga "The Crew That Never Rests" {ihnp4|uunet|rutgers}!cbmvax!daveh PLINK: D-DAVE H BIX: hazy "I can't relax, 'cause I'm a Boinger!"
