RE: Suggestions on HP21 restoration
I agree, EdS2. It looks like an AVR is enough, but I'll try to confirm.

I'm familiar with the smaller AVR ATMega chips, they run at clock speeds from the kHz range up to 20MHz. There are options with 32kb of flash memory and more, and from 512bytes of RAM and more. I'll try to research what kind of precision I can get with this hardware.
