According to [0], TI were launching new graphic calculators with Z80s as late as 2016 - the TI-84 Plus CE-T Python edition (which is still available on Amazon UK[1][2]!)

Not a hugely compelling argument for "the z80 is still a popular microcontroller", mind.

[2] Mild cheating going on though because it runs the Python on an ARM copro.

Well, Z80-compatible but more efficient processors, sure. That pretty well counts because you can still run your own software on them, such as KnightOS, but KnightOS can't compile itself, and I don't think CollapseOS will run on a TI-84.

Collapse OS runs on the TI-84+ but doesn't implement mass storage on its flash yet, so it's not self-hosting on that target.

Thank you for the correction!
