An ode to Apple's ADB mice
The Apple Desktop Bus Mouse and the Apple Desktop Bus Mouse II.
Especially the gamers among Mac users soon found that the standard one button mouse they had received with their Mac was not good enough to play games like Starcraft or Quake 3, well at least that is what they think. Whenever it comes to changing to a new mouse, you'll often find the new mouse has some pros and cons. One of the cons that can often be seen is that many third party mice don't seem to be as accurate and well tracking as the original ADB mouse. Indeed these mice are alltogether very nice products and are in any way far superior to Apple's "Hockey Puck" USB mouse. This mouse too is very accurate for a non infrared-optical mouse, but the shape is simply stupid, you'll lose track of directions very soon, as the mouse turns in your fingers. In the following article I'd like to show the differences between the different series of ADB mice, what problems may occur and how you can solve them.
look back in time
I haven't been lazy and have tried to document the different kinds of mice I have stumbled over since I started using Macs, surprisingly enough, I found as much a 5 different models. Some vary only slightly, some are quite different.
|All the 5 mice seen in chronological order from top down...||...and bottom up.||The two ADB Mice dating back into the 80s, they vary only slightly and the handling is the same.||The oldest ADB Mouse II I found. It features the same Logitech chip as the old ADB Mice.||
A newer version is completely different, the hardware seems to be Mitsumi.
The latest Logictech model, after this one, Apple shipped the iMacs and B/W G3s with USB mice.
There are usually only 2 problems that may arise with Apple's mice:
the second problem is only a matter of cleaning your mouse's wheels from
the crusts of dirt, skin and hair (those aren't necessary rubber rings!),
the first problem requires you to open up your mouse.
There is another possible reason for a bad clicking mouse however. That tiny little switch inside has 2 elastic metal pieces inside, that actually make it switch and click (the sound). If these have worn out, the contact my no longer be granted. To solve that problem, you can open the switch up carefully and try to disassemble, bend, and reassemble the switch. I fixed one of my Diablo-victim mice like that, but be warned: That switchlet and those metal pieces are incredibly small and I spent about 2 hours trying to get it back together. But it is an option. Also make sure you know how the switch was when it was intact, the pieces tend to jump out of position as soon as you open it. Remove the cover of he switch on both sides at once, do not rock it off, or the switch will mess up inside.
That is more or less how the switch looks inside (side view).
that's it about ADB mice already. I'm telling you, they are great. I'm
playing Quake 3 with one of them every day, it owns!
