Casio Z-7000
Casio XL7000
AST GRiDPad 2390
The Zoomer and authorized clones were preceded by the GRiDPad; both designs lead by Jeff Hawkins (The GRiDPad 2390 model is a Zoomer rebranded). The GRiDPad was fully MS-DOS based, the Zoomer, 2390, and later clones were Datalight ROM-DOS v3.31 based and ran a version of Geoworks 2.0 (by the Geoworks company) that was dependent on ROM-DOS. Palm provided much of the software including the PalmPrint handwriting recognition tool, later replaced by Palm's Graffiti. Casio engineered the hardware and BIOS. The official Penright! software development kit was provided by Geoworks and included a Zoomer simulator. The follow up to the Zoomer was to be the Zoomer II. The technology was purchased by Palm Inc who weren't completely satisfied with the design. Hawkins lead the modification of the design that came to be known as The Palm Pilot.
All software, accessories, and peripherals are interchangeable between the various authorised clones.
