Hackaday Retro Edition: Pen Computing

Although we’re well past the heyday of ‘pen computing’, and seemingly into a retro revival with laptops and tablets that come with Wacom styluses and digitizers, this doesn’t mean the pen computers of old weren’t useful. While they were mostly used for industrial applications, they were useful and some of the first practical applications of touch screen displays.

[Jason] got his hand on one of these ruggedized handheld PCs – specifically, an Itronix T5200. This three-pound mini notebook runs Windows CE Handheld PC Edition 3.01. The specs include a 74MHz RISC processor, 16 MB of RAM, 16MB of Flash, and a 7.3 inch monochrome touch screen with 640×240 resolution. It’s odd and old: when closed, it’s over two inches thick. You’ll be hard pressed to find a modern laptop that thick. [Jason]’s hardware is a pre-production version.

Unlike a lot of retro submissions that have somehow managed to pull up the Hackaday Retro Edition on old hardware, this machine actually has a browser. It’s old, it’s clunky, but it works. There are three options for getting this old computer up on the Internet – either IrDA, an RJ11 modem port, or RS232. [Jason] didn’t tell us which port he used to load up the retro edition, but he did send in a few pictures. You can check those out below.

Windows CE On A Raspberry Pi

From all the BSDs and Linuxes to extraordinarily odd operating systems, it seems just about every OS has been ported to the Raspberry Pi. All except Windows, that is, but a few people are working on it.

This build comes to us from [ideeman] who wanted to show off his Raspi running Windows Compact Embedded. It technically works, but there are still a few problems. In his own words:

Unfortunately, as it is now, I can’t really control it through anything else than via the kernel transport layer (through serial, directly to visual studio, and I still get lots of checksum errors, must me from the cheapo USB<==>TTL 3.3V adapter I’m using). The original developer (dboling) is still struggling with native USB drivers, but as you can see, he already got a (unaccelerated) running display driver.

If you’re interested, I can send you the compiled kernel image, but I don’t think you’ll do really much without the serial debugging provided through Visual Studio 2008 (+Platform builder 7.0)… I’m not sure it can be legally released to the public though.

While running Windows Compact Embedded isn’t as cool as running Windows RT on a Raspi, the latter will never happen. Windows RT requires 1 GB of RAM and a 1 GHz ARM v7 processor, neither of which the Pi has. Still, it’s a very impressive hack and with a few more devs on board, [dboling] and [ideeman] might end up with a truly functional system.

Below are pics of [ideeman]’s Raspi running WinCE. For [ideeman], feel free to link to a torrent in the comments.
