The Datalux SpaceSaver, introduced circa 1988 as the Mechanical Enterprises Microtype Space-Saver Keyboard, is a long-standing family of compact keyboards from Mechanical Enterprises (MEI) and its successor, Datalux. Three form factors are available: desk model, tray model, and panel model; each form factor supports an optional Cirque GlidePoint trackpad in place of the central navigation cluster.
An infrared wireless version was available in the form of the nVIEW Toteboard.
Description
All three variants conserve width by placing the function keys, navigation cluster and number pad behind the alphanumeric area in four rows: the keyboards trade width for depth. Keycap spacing is standard 0.750″ (19.05 mm), but row spacing is reduced to 0.625″ (0.588 mm) to compensate for having nine rows instead of the usual six.
All three types use flat profile keycaps; the tray and panel versions are completely flat, while the desk model has an ergonomic ramped backplane that elevates the rear half of the keyboard in line with its space-saving arrangement.
Datalux SpaceSaver keyboards have been made with both MEI and Cherry ML switches. There is a general preference of the ML switches over the MEI switches in terms of feel.
On XT/AT switchable models, the keyboard protocol was selected using a jumper under the 1 key.[2] Current models are USB.
