I've gotten so many requests for this information that I'm just going to post it here. The only stuff in all this that I will probably use is the info about the switches from DigiKey. Chris Vaughn So here's the stuff: ------------------------------------------------------------------------------- In comp.sys.amiga you write: >What's the best thing to do about a broken mouse? (besides yell & scream) >My left button just died. Is there any point in trying to repair it? >Or should I just replace it? If so, with what? (i.e. what mouse is best?) >Thanks bunches, I'm dead in the water till I get this fixed... >-- >------------------------------------------------------------------------------- >Chris Vaughn | Hmmm... what to put here.....?? >Junior in Computer Science | >University of Kansas | >vaughn@kuhub.cc.ukans.edu | >------------------------------------------------------------------------------- Here is a reprint of Riyadth's mouse article: Path: drivax!amdahl!apple!brutus.cs.uiuc.edu!jarthur!uunet!tut.cis.ohio-state.edu!ucbvax!ucdavis!csusac!riyadth From: riyadth@csusac.csus.edu (Riyadth Al-Kazily) Newsgroups: comp.sys.amiga.hardware Subject: How To: an inexpensive mouse upgrade/replacement Message-ID: <1990Feb5.083013.4450@csusac.csus.edu> Date: 5 Feb 90 08:30:13 GMT Distribution: usa Organization: California State University, Sacramento Lines: 81 Inexpensive replacement Amiga mouse How-To After having come across the specs for the Logitech P7 bus mouse, I made the discovery that it's operation is exactly the same as described in my Hardware Reference Manual for the standard Amiga mouse. I happened across a stash of P7 mice at HSC Electronic Supply in Santa Clara (see address etc. at the end of this document). Unfortunately the mice are only the two button variety, but the price was right, and it is definitely an improvement over my original mouse - real switches in the buttons even! The mouse is your basic Logitech-type mouse, model number P7-2F-SI. The P7 is the type of mouse (Amiga compatible, bus style), the 2F means that it has 2 buttons (I dont know what the F stands for, do any of you?). The SI means that it was custom made for Systems Integrators. The mouse cord ends in a modular connector with 8 conductors. In order to connect it to the Amiga, a female DB9 must be connected, either by cutting the modular plug off and soldering on the new connector, or (the way I did it) by getting a modular DB9 adaptor, available at HSC. With this particular mouse there is a slight electrical modification that must be made for proper operation. Actually, it is an un-modification, as the mouse was modified for Systems Integrators' application. There is a trace on the mouse circuit board that has been cut and jumpered. To use the mouse on the Amiga, the jumper must be removed and the cut trace restored to it's original route with another jumper. Then all that remains is to route the 8 conductors in the wire to the correct 8 pins on the Amiga's mouse port. The connections should go something as follows: Amiga pin # function P7 wire color 1 V-pulse brown 2 H-pulse grey 3 VQ-pulse green 4 HQ-pulse yellow 5 middle blue (does not apply to this mouse) 6 left black 7 +5v white 8 GND pink 9 right clear Note that the colors given may not be correct for all mice, so you may want to open it up and check. The following is a pseudo-diagram of the circuit board with colors in their appropriate place: | L-BUTTON R-BUTTON | | (top row) ___ (bottom row) | /___ | white o/___o- brown | green o/___o- yellow LOGIMOUSE | grey o/___o- pink P7 | blue o/___o- clear REV D | black o/ o- red (shield gnd) | | +---------------------------------------------------------------- And finally, for the information on how to get this mouse. Firstly, the cost of the mouse was $7.95, and I was able to find one new in it's original packing box, although many were out of the packaging. The address of HSC is as follows: HSC Electronic Supply 3500 Ryder Street Santa Clara, CA 95051 orders - (800) 4-HALTED in CA - (408) 732-1573 customer service - (408) 732-1854 Minimum order is $10 + shipping, $2 fee for orders under $20. Don't forget to order DB9's and hoods if you need to bring your order over $10, or order a couple for friends. Have fun with the mouse. Now if only I could find a 3 button P7 lying around... ------------------------------------------------------------- riyadth alkazily {ucdavis,lll-crg}!csusac!riyadth Path: drivax!amdahl!apple!snorkelwacker!bloom-beacon!eru!luth!sunic!log-hb!nftcon From: nftcon@log-hb.se (Conny Ohstrom) Newsgroups: comp.sys.amiga.hardware Subject: Re: A quadraplegic mouse! :-) Summary: SUN optical mouse amiga Message-ID: <10938@log-hb.se> Date: 5 Feb 90 15:40:44 GMT References: <2869@bingvaxu.cc.binghamton.edu> <3835@hub.UUCP> Reply-To: nftcon@log-hb.nynashamn.telelogic.se (Conny Ohstrom) Organization: TeleLOGIC AB, Nynashamn, Sweden Lines: 19 If you can get your hands on a (cheap) SUN-mouse type 'm3' then get it instead ! you just have to connect a 9 wires between a female DB9 and a internal row of solder-blobs. inside the sun-mouse: 10 09 08 07 06 05 04 03 02 01 | | | | | | | | | | female DB9: 02 07 08 04 03 01 06 05 09 if any have a solution how to connect a 'm4'-type of mouse, I would be very intressed how to do it. exit 0 ; --- Conny Ohstrom,Televerket Farsta HK,farnebogatan 81-87, s-123 86 farsta,sweden usenet: nftcon@log-hb.nynashamn.telelogic.se, phone: +46 8 713 40 31 -- exit 0 ; --- Conny Ohstrom,Televerket Farsta HK,farnebogatan 81-87, s-123 86 farsta,sweden usenet: nftcon@log-hb.nynashamn.telelogic.se, phone: +46 8 713 40 31 end of excerpts.

Panasonic Momentary pushbutton switches Part # P9950, Price: $.39/ea. All you do is un-solder the 4 legs of the switch, and then re-solder the new one in. Nothing else is needed.

Soldering is required, but it's easy soldering (no ICs to overheat or anything). The hard part is finding a replacement switch. I bought a couple of these for less than $5 each from George Gibeau (ggibeau@ucqais.uc.edu) who bought a mess of them from somewhere. Drop him an Email, maybe he has some left or can point you to a source. I'd recommend going the repair route, unless you are really fed up with that mouse and want a different one anyway. By the way, as an emergency measure, I believe there is a keyboard equivalent for generating a mouse click but I can't recall it exactly; l-A/l-alt/something.

Until you get a new mouse, pressing the left-alt and left-Amiga keys will work just like the dead left button. -Steve Holland -------------------------------------------------------- Steve Holland 22 Forty Acres Dr, wildcat!steve@alphalpha.com Wayland, Ma 01778 NOTE: "alphalpha.com" may soon change to "alfalfa.com" -- ------------------------------------------------------------------------------- Chris Vaughn | Hmmm... what to put here.....??
