Re: A New (To Me) Microsoft Trackball Explorer

Among Elecom products, Deft Pro is quite close to the MTE in design and controls (buttons, wheel) placement.

Re: A New (To Me) Microsoft Trackball Explorer

Congratulations! :) IMHO, it's one of most convenient trackballs (except for strange Microsoft's decision to put its right button on the left side - but it's easy to reassign in software), and even today it's still quite usable. Steel bearings wear quickly, but after putting ceramic or ruby ones ins...

Re: Measurement Systems 3" Trackball and RAM Optical Instrumentation Controller

Are you familiar with any smaller active serial converters that could be installed inside a device so that the keyboard + trackball connections could be internally converted and combined using a small USB hub so the whole thing would only use 1 USB port?

Mine seems to have a few chips inside, but they might for be the buttons, guess I need to break out a voltmeter.

Re: Measurement Systems 3" Trackball and RAM Optical Instrumentation Controller

Do you mean replacing the controller with a microcontroller or reading the outputs at the plug? In case of quadrature output, there's no controller in device typically - so I'll have to add one. Any idea what to do about the disintegrating roller foam? I'm thinking glue or doublesided tape and a st...

Re: Measurement Systems 3" Trackball and RAM Optical Instrumentation Controller

3 inches is extremely entertaining, but could be a pain in daily use. -snip- the switches are backlit and stupidly tall for the amount of travel. Depends on particular use case, I believe. Trackball of such size/shape probably was never intended to be used as a pointing device for computer GUI cont...

Re: Measurement Systems 3" Trackball and RAM Optical Instrumentation Controller

The mechanism is also different from conventional track balls as it uses servos(?) or some other sealed component instead of spoked wheels and optical encoders Actually, no difference here. They're the same quadrature encoders, just in different (sealed) form, like this: https://www.bourns.com/prod...

Switches could be a bit lighter and more silent.
That's my opinion, too. I dislike noisy things, so I've slightly modified my SlimBlade to be almost completely inaudible:

Re: Trackball for smaller hands

For your wishlist, I'd suggest to try Elecom Deft Pro. IMHO, it's currently the best & feature-rich model available. As for now, I have SlimBlade at work and Deft Pro at home, so probably can compare them. Unfortunately, there's several reports about Elecom quality problems recently, but my particul...

Re: Ch MVP Trackball

Having both, I'd say CH is much more usable than ITAC on modern systems. Of course I keep it in doubled resolution mode, but even native one outperforms ITAC's 192 PPR. Mechanically they're nearly identical: exactly the same type of bearings & shaft diameter, but CH have slightly bigger ball and bet...

Re: Ch MVP Trackball

Regular plain vanilla ball mouse. Dirt-cheap or free nowadays. It uses the same quadrature detectors and slotted shutter discs as your trackball: you'll just need to re-wire things.

P.S. Avoid Logitech mice, as many of them use proprietary detectors, not discrete quadrature ones.

I doubt you'll be able to find a converter: Sun always was a "niche market", and prior to your CH it was only ITAC known to me who made compatible trackballs...

Very unlikely indeed. Never owned SGI, but on old Apple machines serial pointing devices were not normally supported, at least by MacOS itself.
