Curtis MVP-1

Main article here: https://forum.trackballs.eu/viewtopic.php?f=17&t=15 There's almost no need to change mechanics of this device. The only improvement I've done is addition of fixing C-rings to the supporting bearing. Without that, it had too much axial play, rubbing the edges of support cage. Rings...

The problem in most cases is caused by original lubricants: decomposed, dried out, contaminated etc. It's possible to just replace them, but high-grade bearings are expensive, and some sizes difficult to find...

Variants

For good trackballs, there are two main kinds of ball retaining/bearing designs: rotating rollers or gliding beads. They're very different in terms of feel: rolled ball easily rotates in two directions, while gliding ball moves in any direction, including twist motion. Both designs have advantages a...

Reasons

As for me, there are two main factors: 1. There are many great old models with fine mechanics and nice ergonomic shape - but interface is outdated, and/or resolution too low to be usable on contemporary systems. Typical 200 pulses for revolution value was totally sufficient for 480x640 screens, but ...
