The finest rugged computers

An industrial Psion Epoc pen computer released in September 2001.

Psion Teklogix netPad

Rugged water resistant pen tablet with a half VGA 640 x 240 backlit 256 colour display, dynamically switchable from landscape to portrait format. It is somewhat larger and heavier than the Psion 5 range, at 215mm x 85mm x 25mm, and 508 grams with battery (8.47 x 3.35 x 0.99 and 1.12 lbs). It was designed by Psion Enterprise for industrial use, and is water resistant and designed to withstand a drop of five feet, with an IP67 rating.

There is an on screen keyboard using the touch screen display, and it comes with a pointer.

It has an Intel SA-1110 Strong ARM CPU running at 206MHz, with 16 MB of internal flash ROM, and 16 MB or 64 MB of SDRAM. The add on external memory is via a MMC memory card, not the Compact Flash used by the Series 5. It cold boots from the MMC using a single operating system and applications file. Supplied with a CD of applications for enterprise use and modification, and a SDK, since it would normally contain custom applications.

It has an IrDA 1.1 port capable of 115 kbps, as is the serial RS232 port. It has 8 bit sound with microphone and loudspeaker. Like the netBook, it is powered by a 875mAH replaceable rechargeable Li-Ion battery for 8 to 10 hours, with an optional 1400 mAH battery pack available. The backup battery will retain data for up to 48 hours. There is an external battery charger that works through a docking adaptor.

Software is ER5 (not ER6) with JVM 1.1.4. As an industrial design, it has a user configurable operating system loaded into Flash memory, like the netBook. Applications supplied on CD are Mail, Web, Word, Sheet, Contact, Agenda, Jotter, Voice, and a software keypad.

There are five models. The 1100 has 16 MB SDRAM, and lacks navigation button and the two progarmmable softkey. All other models have 64 MB SDRAM. The 3500 and 3700 models have the 1400 mAH battery pack, to assist with the Symbol 923 barcode scanner they include. The 1200 and 3500 model have a transmissive (indoor) display. The 1400 and 3700 models have instead a transflective (outdoors) display.

Although originally apparently designed for a mid 2000 release, the netPad was not released until 28 September 2001. Prototypes were known to be working prior to the end of 2000.

I got my original material from but the netPad site seems to be

This site will look much better in a browser that supports W3C web standards but it is accessible to any browser or internet device, including Psion Web and similar PDA or limited browsers. Netscape 4.x users - turn Style Sheets off. Your style sheet support is too broken to use (sorry). -> epoc -> epoc hardware -> netpad
