I initially was going to use this one (it's great of course as it shows it only took 1 machine to change their mind...) but decided the HP-10 is even more interesting, since most folks think the Pioneers (10B, 14B, 20S, etc.) were HP's first non-RPN machines.

Apart from some desktop machines and the HP-01.

I think I've got three of them, don't remember if I have a printed manual... should resort to a PDF.
