I was part of the core development team for the handheld device Ramses, later named MNCI-RX by the sales people.

Ramses With just 3 people in the core team we developed Ramses as a powerful gadget with lots of built-in hardware. Our target markets were the transportation, logistics and warehouse industries. It could both work online and offline. It was freely programmable and very versatile.

Some of the technical specs was really outstanding for such a small device at that time.

Newer devices and also the European ecological ROHS directive eventually killed this device.

Any customer can get all of this (and more) in source code.

I've done all the low-level stuff (cross-compile environment, hardware test environment, Bootloader, Kernel, Filesystem, Qt/Embedded adaption, Ramses SDK documentation) and a good share of the high-level stuff like 802.1x, VNC-Server, Signature recorder, Qt/SQL proxy, IPKs...
