Whats the latest on spinner speed sensitivity on the Z axis.

Update:
I'm trying to run a version of mame newer than is supported by the current Z axis diff.  I dropped a line to u_rebelscum to request an updated diff.  I'm assuming he/she is busy in the real world, so I'm going to delve into making the change to mame source to divide z axis input by 4.xx by hand this weekend.  I'll report results back here.

Further update:
Bagged it, got out the soldering iron and switched to X axis.  Much better and easier. Z axis is more trouble than it's worth if you're on XP and current (144) mame. 
TopJimmyCooks:
If both a trackball X axis and turbotwist spinner are connected to the Optiwiz 1.0, Do I need resistors on the trackball leads or something?  right now my trackball's working XY but my turbotwist on X isn't working at all now.  Thought it was but i may have been moving the TB or mouse.

This won't work.  If you want to use the X axis for each device, you will need a DPDT switch on the output lines in order to switch between the two devices.  Otherwise, each device must have it's own axis connection,

Ug.  OK - I need to decide between getting another optiwiz and running two or delving back into compiling the Z axis divide by four thing.  Thanks for your help, Randy.
