old CPUs in calculators

[jxu]

I was considering getting a Raspberry Pi, but then I felt a sudden urge to stick to classics. I considered out buying an old chip to experiment with, but then I realized something from a while ago:

Ti-83, Ti-84 Plus: Z80
Ti-89: Motorola 68000

Assembly shells and libraries are also available. Maybe I can do some cool asm coding with these in mind

Ti83 still does everything you need a calculator to do

6502, only cool retro chip.
