#HewlettPackard #calculator #HP16C

I think I've finally figured out how to hack the HP-16C microcode to support more user RAM than the original, which had only 203 bytes. I first studied this in 2004-2005, but at that time was only able to understand the HP-15C firmware enough to patch that.

Starting the day with another 🇨🇦🦖 moment.

@hackaday in reference to the HP16C calculator stated:

Most surviving examples in the world are well-used

So I reach into the hanging pocket beside the couch...

@Raspberry_Pi Oh, wait!
#HP11c joins the #HP16c, too.
Best calculators ever.

@Raspberry_Pi No need to remember. It's here. 😉
