1994 — Truedox/Memorex trackball

The Truedox model 300 trackball was produced by Truedox Technology Corporation in Taiwan. The manufacturing company not only sold the device under its own name, but also actively provided it for rebranding, as a result of which the model 300 is more common under other names, such as Memorex or Sunnyline, than under the original brand. In particular, this copy was sold under the Memorex brand, owned by the Californian company Memtek Products inc.

The body of the trackball is asymmetrical, made in a minimalist style of glossy white plastic with a brown insert.

The trackball packaging and user manual of the Memorex variant use the “Stationary Mouse” subtitle, apparently borrowed from the Logitech TrackMan Stationary Mouse trackball released a year earlier, and emphasize its ease of use in a limited workspace.

The trackball is right-handed and the shape is largely inspired by the Logitech another product – LOGiTECH, which is also designed for a horizontal position of the hand and the rotation of the ball with the thumb. According to Logitech, this shape is better suited to the anatomical structure of the hand (in the advertising, the shape of classic symmetrical trackballs was opposed to a similar shape as a “device for aliens” [1]Not every kind of pointing device fits your kind of hand (LOGiTECH TrackMan tadvertising). //PC Magazine.

The trackball internals reveal an opto-mechanical device typical for the beginning of the 90s, in both the encoder implementation and the whole internal layout, which leaves a significant amount of empty space inside the case.
