It is an RPN calculator aimed at computer programmers with support for hex, binary, octal and decimal and all sorts of useful operations like bit shifting, masking and rotations. I don't own one myself, I have a [Swiss Micro's DM16L] (https://www.swissmicros.com/en/products/dm16l), a high quality modern day remake with improvements like a 2 line display. There is a limited run [collectors edition of the HP 16C] (https://hpcalcs.com/product/hp-16c-collectors-edition/) coming soon though. But none of those calculators run Linux. This post goes into detail on my updated linux port for the HP Prime G2. The HP Prime G2 has a 528 MHz ARM Cortex A7 CPU, 256 MB of RAM and 512 MB flash. My updates linux port includes a touchscreen driver for the Ilitek ILI211X, better keyboard support, working X11, Doom and a C compiler. This post also covers other calculators and a Windows port for the Prime G2.

This is a bike computer, a navigation device for cyclists, made by MiTaC, the same company that makes the Mio bike computers. This Navman Bike 1000 is a rebadged `Mio Cyclo 200`. It's from 2015 and as you might have guessed, no more map updates. This article shows how I dabbled a bit in reverse engineering, figuring out the device runs Windows CE 6.0 and using Total Commander and [NaVeGIS](https://sourceforge.net/projects/navegis/) together with Open Street Map to get up to date maps from the OpenFietsMap project, allowing me to use this device for navigation with the most up to date maps. Since it is all open source, even if the current map provider would stop, I can always make my own maps. Fri, 25 Jul 2025 23:37:00 GMT Sat, 02 Aug 2025 21:31:00 GMT
