You've got the 2 MIDI ports (the - basic spec of which looks noisy I might add -- not Atari's fault), - an RS-232C, semi-SCSI, Centronics, 2 joystick and cartridge port. - Take that "Centronics" port. The original Centronics used every - other wire as a balance which could have helped cancelled "some" - RFI (doesn't help that much anyway really). And I bet the TT with all its ports causes lots more problems. -- Ed Krimen ............................................... ||| Video Production Major, California State University, Chico ||| INTERNET: ekrimen@ecst.csuchico.edu FREENET: al661 / | \ SysOp, Fuji BBS: 916-894-1261 FIDONET: 1:119/4.0
