You may soon want to start charging me for answering all of my qustions.
Thanks for showing up again.

You're welcome.
I'm not helping fix this problem very much, though. :-\ (see below)

Based on this, do you then think it's most likely a hardware limitation?
In that case, I will probably face the same issues with other serial mice.
Also check my answer to Alan's reply.
Thanks.

It's Windows XP.
I checked if I could change those settings as you said.
It can be done for the PS/2 mouse but not for the serial.
It looks like I'm out of luck there.

Hmm, looks to me like either a driver or, more likely, a trackball hardward limit. My guess is since you can't set the mouse refresh rate via the driver, either the driver sucks, or (more likely) the TB has a low fixed speed when plugged into the serial port.
I don't have one of those TBs, though. Maybe someone with one can confirm that the serial is slower than mouse port on this specific device, or be of more help on it. (As I posted before, though, serial mice are often slower than mouse port mice.)
You might be able to do better with a serial mouse to hack as the spinner. However, a safer thing, especially with a winXP system, is do the spinner in USB instead of the mouse port, and leave the TB at it's better port. :-\

There is another alternative which I discussed in this other post:
http://www.arcadecontrols.org/yabbse/index.php?board=1;action=display;threadid=7893
It's a long thread so I'll summarize it:
I'm basically considering using a spare PS/2 mouse I have
and wire its opto-electronics hack-style to the trackball PCB without disassembling the spare mouse in case I need it later for a direct connection to the PC.
As a result of discussions on that thread it looks like the only problem would be that the PC could get confused if it sees both PCB's. I'm thinking maybe I can drill through the conductor tracks on the PCB's to isolate the diode and receiver and power them by direct wiring from the trackball PCB. If I ever need the PCB working again, I can always re-fill the holes with soldering tin.
Does this sound like it's possible?

It would be a bit of work but it should work. I think you'd have to wire power to both the emitter and the detector, ground to the emitter and 2 signal wires to the detector. Might be better to try and cut the traces with a razor knife instead of drilling them out. Another option is to get an optic board somewhere (like oscar's or happ's universal optic boards) and use that.

The razor knife is a good idea.
The detector will need ground too, although your probably taking into account the on of the signal wires will be ground?
I'll look into oscar's boards. Thanks for pointing that out.

The detector only has 3 pins on it. Power and 2 signal. No (separate) ground required. Emitter has 2 pins, power and ground.
