SGI Compatible Trackball

[David Richardson]

  This is in response to Dale Olson's request for an SGI 
compatible trackball.  I thought it might also be of interest
to others.
  We've found a "plug-and-play" trackball for our 4D/25.  It
plugs into the same port as the optical mouse with no changes
necessary.  It also has 3 buttons that function the same as the
optical mouse.  Ergonomically, it leaves something to be desired
compared to other trackballs I have seen, but this is the only
one we've found for the SGI (except for the expensive SpaceBall).
Here's the info:

	What:	Mouse-Trak Model #M5-S.G. for SGI 4D/20
	Where:	ITAC Systems, Inc.
		3121 Benton St.
		Garland, TX	75042
	Price:	$199 (June '90)

  I'm sorry I don't have their phone number anymore.  You'll
probably have to try Information.
