As far as calculators go, the HP 20b Business Consultant Financial Calculator isn’t worth a second glance for someone working outside of the finance industy, but it could peak the curiosity of those who like to tinker with their gadgets. The calculator features an Atmel 30MHz, low-power AT91SAM7L128 ARM7 System on chip processor and according to Slashdot “it has a bootloader and JTAG interface to allow user applications to be written and downloaded…” HP has even released an official devkit for the HP 20b which according to the site is “designed for developers who want to re-purpose the HP 20b and reuse the platform for other purposes.”
I haven’t really come across any examples of how the HP 20b has already been re-purposed in an interesting way, but there’s an ‘HP-20b Repurposing Project‘ wiki already setup that includes guides on the calculator’s hardware specifications, what hardware you’ll need to tinker with it and even instructions on how to open the case. There’s also a handful of downloadable software demos that don’t look that exciting (SRAM resident battery level display demo) but I’m sure will come in handy for developers writing their own code.
