Hutzelman) Newsgroups: comp.sys.apple2 Subject: Re: ADB Joysticks (was:Re: Space Ace (was Re: soundsmith question)) Message-ID: <0b6aHKa00Vp30lAW8N@andrew.cmu.edu> Date: 16 Oct 90 01:39:34 GMT References: , <9010132252.AA02397@apple.com> Organization: Carnegie Mellon, Pittsburgh, PA Lines: 14 In-Reply-To: <9010132252.AA02397@apple.com> The internal game port on the ][, ][+, //e, and IIGs (that's the 16-pin DIP one) has 4 annunciator outputs, which ARE used; just not by joysticks. They could not be easily converted to inputs without breaking existing hardware that uses them. Also, the //c and //c+, and the external (DB9) game ports on the //e and IIgs don't have the annunciators at all. They also don't have the second 2 paddles and, depending on which machine, may or may not have the 3rd switch input. ----------------- Jeffrey Hutzelman America Online: JeffreyH11 Internet/BITNET:jh4o+@andrew.cmu.edu, jhutz@drycas.club.cc.cmu.edu, jh4o@cmuccvma >> Apple // Forever!!! <<
