Anyone with a trackball that has a PS/2 cord use a mouse hack?

I have done several mouse hacks with a Betson TB unit.  Some mice work great and some do not.  It is really a trial and error hack because you do not know how well the mouse will work until you finish it.   I have found that the simpler the mouse the better my results have been.  Get a cheap PS/2 mouse and give it a try.  You will have to bypass or disconnect your existing PS/2 controller.

There are many possible sources of backspin, as it's caused by whatever the biggest bootleneck may be for each hookup:

* Optical sensors (very rare actually, unless see next)
* Improper match of tooth/gap spacing and sensor spacing
* Optical PCB circuit (if any, and more likely with worn solder or components than the chip speed)
* Communication protocol (IE: serial more likely than USB, slow poll rate more likely than fast)
* Motherboard I/O buffer (most MBs are fine, but a very few just suck)
* OS and OS mouse driver (IME, fights with protocol as biggest bottleneck)
* Application (if doesn't poll enough)
* mouse speed & "enhanced precision" settings in mouse controller
While more teeth might cause the second bottleneck, and contribute to anything downstream, it probably won't have any effect at all to the back spin.
