Real Input Hardware For The Mac
I recently inherited a nice 500MHz Blue (okay, Indigo) iMac
from my employer. It had a problem with staying powered on. I found the problem
to be bad solder around the power cord connection and fixed it right up. Now the
machine functions perfectly and for a change I got the Apple mouse and keyboard
with it. And since Apple released a "real" OS with the advent of OS X, I was
thinking of at least learning the new system. And learn I did...when I wasn't
using iTunes... ;-)
Unfortunately, unlike previous generations of Apple
keyboards and mice that I have used, these new USB units from Apple seem a bit
on the cheap side as build quality goes. The keyboard is apparently not well
sealed against dust and beverage entry (a big no-no on both counts) and the
"early" revision black USB Pro Mouse seems to like to develop a bad spot in the
USB cable. Mine did just that and oftentimes the mouse would just quit
responding for a few seconds.
The keyboard crud didn't really bug me that
much, because the keyboard is black in color and hides most of what's been
dropped inside. It also hides the fact that people usually don't wash their
hands before typing. (The white keyboards are not like this. I am glad I do not
have one as they stay new-looking for all of 5 minutes after you open the box.)
But, I figured, if I was going to do something about the mouse, I should do
something about the keyboard as well since it also seems to be cheaply
made.
Apparently you can fix the problems with the keyboard
and mouse. At
least two kind souls on the WWW have posted very nice instructions for doing so.
The only trouble is that I'm cheap, I want it fast, and I'm not the world's most
careful or coordinated person. That last fact was a show-stopper. Both repair
methods require a fair bit of care and steady hands, which I haven't really got.
(No, I'm not a "spaz" but I do have a very minor shaking in my fingers at almost
all times...it runs in the family.)
So my answer was a Belkin PS/2 to USB
adapter. I already had this adapter handy from another project, and I have plenty of
PS/2 mice and genuine IBM Model M keyboards sitting around.
I shut down
the Mac and disconnected the stock keyboard. Then I plugged the Belkin adapter
in followed closely by an IBM Model M keyboard and a plain old Microsoft PS/2
mouse.
I powered up the Mac. Everything seemed to work, but the mouse was
jumpy and often acted as though it were being right clicked. (Some other testing
seems to indicate that this adapter doesn't like MS Mice as many different
revisions from over the years were tested with identical results...) The
keyboard worked just fine, something I considered a minor
miracle.
Swapping to a generic IBM "soapbar" mouse solved the right
click and "twitch" problem. You can see the final setup by clicking here.
Now of course
there are no special Apple keys on this keyboard, but so far I've been getting
along OK with it. I usually work with the machine over VNC from a PC anyway, so
I don't miss not having the Apple keys too much. If it really bugs me, I may
pester the author of DoubleCommand to see if the
volume and "Apple" keys can be remapped somewhere else.
(I have also
noticed that certain keys on the IBM keyboard either do nothing at all or have
strange new functions that I'm not sure Apple really intended for any keyboard
to have!)
Now that the new keyboard and mouse were in place and working,
there was really nothing left to do other than to make the mouse atone for its
sins!
Okay, so I didn't really do any of those things...but
it made me feel a lot better to take the pictures above and channel off some
other angry thoughts. I set the stock keyboard aside as there is nothing wrong
with it and someday when I have too much time on my hands I'll work at fixing
the stock mouse.
