For a relatively inexpensive alternative, contact Vernier Software at
[phone]. They're a company that got their start making scientific
sensors and programs for the Apple for use in schools. They still sell
Apple stuff, as well as IBM and Mac modules. They have a voltage sensor
that connects to the game port for $45 assembled, $30 in kit form.
You might also try a similar company, PASCO, at 1-800-772-8700.

The Apple IIgs can use some Mac ADB mice, trackballs, touchpads and
miscellaneous other ADB devices (note: there is a separate list for
keyboards). The following ADB devices work with the Apple IIgs.
'Reviews', where available, are included. These reviews, solicited

LogicTech 3 button MouseMan (M/N M-AC13-4MD) (Made in Ireland)
[Tony Cianfaglione]
I use a Logitech ADB three button mouse with my GS and all
three buttons function well. The left button selects the
item, the middle button scrolls left or up and the right
button scrolls down and right among the GS desktop items
such as Finder lists or lists of items in programs such as
Print Shop GS and Appleworks GS.
The two scrolling buttons also work on any GS finder list.
It comes in extremely handy when scrolling through
subdirectories containing hundreds of files. You can
scroll a lot faster and with much more precision that you
can by using the up or down scroll buttons within the
window itself.
My GS is accelerated to 13.75 mhz and the scroll function
is fantastic. The 3 button mouse is the way to go as far
as I'm concerned.
Mouse Systems ADB Little Mouse (M/N 403323-001) [Don V.
Zahniser]
An optical mouse that is slightly smaller than the standard
Apple mouse. The mouse button is larger than that of the
Apple mouse, covering about the front 1/3 of the mouse
body. Switch action is more sensitive than the Apple
mouse. Comes with a metal mousepad with an imprinted
pattern that the mouse responds to. Felt strips on the
bottom of the mouse make it self-cleaning. 'Faster' than
the Apple mouse (less movement of the mouse for the same
cursor movement) and ultra-reliable.

Message 62 Sat Dec 03, 1994
Shopping tip for you. . . I was at Computer City tonight
and picked up a "precision instruments" brand mouse which
is two buttoned (one for chording) and, not only was it
cheap (29.99), not only does it work, but the documentation
actually says (verbatim):
"Your pointing device is compatible with the
MACINTOSH, MACINTOSH II, MACINTOSH IICX and
_APPLE II GS.-"
We do get a little respect, sometimes. . .

Logitech Trackman Marble for Macintosh (P/N 804219-0000) [Don V.
Zahniser]
An ergonomically-designed trackball with 3 mouse buttons
that correspond to the index, middle, and third finger
positions. The thumb moves the trackball (about 1.25"
diameter), which is mounted on the left-hand side of the
assembly. Software is provided for programming the buttons
on the Macintosh, but on the GS, all three buttons act as a
normal mouse button. On a ROM 01, fast mouse speed is fine
for normal use, but slow is better for activities that
require precision. A really nice, comfortable, easy to use
trackball. Does not have a free-wheeling spinning action
as on some larger trackballs. Appears to be immune to dirt
build-up.

Well, there was this really cute little MicroTRAC (by
Microspeed) trackball there, and it sort of followed me
home. It's one of those little thingies that can be used
with laptops, with a total footprint about 2/3 the size of
the mouse that came with my GS. I have it attached to the
side of my keyboard right now. It's a three button mouse -
er, trackball. Left has standard mouse button action,
right is a double-click button, and center (behind the
little ball) is a click-lock button. It's got an LED that
lights up when the mouse button is down (great for those
2am CoPilot sessions ;^). Action on the ball is pretty good
(far better than my defective Kraft), but certainly not as
smooth as the Kensington Expert Mouse that I use on my
Vectra at work. I kinda like it :^)

A quick update on the MicroTRAC -
This little critter has a decided X-Y axis preference; I
think it's because it doesn't have a diagonal idler
bearing. This makes it harder to track from corner to
corner of the screen. OTOH, it is GREAT as a 'mouse' in
AppleWorks, where inadvertant diagonal movement of my mouse
was driving me crazy trying to position the cursor (and
yes, I did play with the mouse sensitivity settings).
The other neat thing about this micro-ball is that I have
it mounted on a bracket from one of the screws holding the
keyboard case together. I work the ball and switches with
my fingers, and my thumb is resting right next to the
