WP34s Programming Cable

[sa-penguin]

Hi, new member here. I hope to be converting a 30b to 34s "soon"...

I'll try using a "bus pirate" courtesy of dangerous prototypes .com and seeedstudio. It does I2C, SDI, serial, even JTAG, and runs at 3.3V. Wish me luck.

A little history: I cut my programming "teeth" on a HP41C, back in 1981. Nostalgia got the better of me recently, and I started designing my own [RPN] calculator. 5 rows of 10 keys, plus big enter, made a 49-key pad on a 100mm x 60mm board. My layout followed the HP12C style, with the final format planned as a clamshell, a bit like the 28C/S.

When I was researching the functions for the keys, I stumbled on the links to the WP34s. Whoa! The only fault I can pick is the display - and now I hear a 43s is in the pipeline. I know it isn't finished - I want one, anyway.
