A friend of mine is trying to build a switchbox to switch the mouse and Joystick on port 1. He is having trouble and I wonder if anyone knows exactly what lines need to be switched? (other than all, of course) thanks!! -Andrew -- Andrew Gillham | andrew%aucis.uucp@mailgw.cc.umich.edu or Andrews University | sharkey!aucis!andrew Berrien Springs, MI. USA! | Signature?

From article <7955@cbmvax.UUCP>, by kevin@cbmvax.UUCP (Kevin Klop): > In article <508@aucis.UUCP> andrew@aucis.UUCP (Andrew Gillham) writes: >>A friend of mine is trying to build a switchbox to switch the mouse and >>Joystick on port 1. > [Lots of pinouts deleted.] What about just switching power and ground? Since the joystick switches are all wired from their output to ground, opening the ground lead will completely disable it. The mouse requires both power and ground, so opening those two will disable it. There is one possible problem with this idea though. Does an unpowered mouse put enough drain on any of the lines to activate them? Since a DPDT (double-pole, double-throw) switch is cheap, it might be worth a try. But what I'd really suggest is buying a DB-9 switchbox. A number of places that advertize in Computer Shopper sell them, some quite cheaply too. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 Here: utah-cs!esunix!blgardne {ucbvax,allegra,decvax}!decwrl!esunix!blgardne There: uunet!iconsys!caeco!i-core!worsel!blaine (My Amiga running uucp) "Nobody will ever need more than 64K."

Here is a similar problem. I have my A1000 stuck in a rather tight location and need several right angle DB2 plugs(like the mouse). Anybody know a source for the housings? I can get about 4 styles of straight housings and solder cup plugs are easy to find but I haven't seen ANY right angle housings for DB connectors of ANY size. I could just make a mold and pot the thing but would prefer to use a commercial housing. Dana FelineGrace @ cup.portal.com
