I am a strong believer in Open Source. The Open Source community have developed the most reliable, flexible, affordable, secure and maintainable systems for general computing use. Many of the reasons for this may be found in the first paper.

Part of my early experience in programming came from using HP handheld and desktop calculators in the early to mid seventies. Back then, any other personal computer which was affordable could do little more than blink lights. (I built some of those too.) So I still have a soft spot for owning and programming these early computers. (I have several HP-41's, HP-48's, an HP-29C, HP-15C, HP-16C and an HP-95lx)
- The HP Museum is a fabulous resource
- Current HP offerings
- HPCALC.ORG for the HP-48 and 49 series
