Franken-classic

[Paul Dale]

I don't have anything planned yet and not sure how I'd find time. It's just something Harald has asked about a couple of times and it seems like it is worth a little exploration. The big limitation will be the fifteen digit seven segment display.

As for hardware, the most obvious choice is the second series HP 35. These have keys that are unmarked and only a faceplate overlay would be required.

My question was really about avoiding this model in favour of a cheaper body and scavenging keys from multiple devices to cobble together so that key stickers weren't required.

Feature-wise, there isn't a limit. Although the display will cause problems (e.g. matrices and complex numbers would be tricky to display nicely).
