It is pretty fun. If you have a TI-83 or TI-84 calculator you can do the same thing a little bit easier.

In high school, I would print out 2 pages of all the Z80 opcodes and put them on my desk during class. The calculators let you directly input hex and then run your program with asm(), so I would write my program by hand on paper, and then next to each line translate it to machine code and put it into the calculator. A lot of TI routines are easily accessible with bcalls, so you don't have to reinvent the wheel with each program.

Plus Z80 is a lot easier than x86. (I still remember the return code: C9)

I had a lot of fun taking friend's calculators and disabling the LCD and power button in assembly :)

Neat. I still have my old TI-83 lying around in my cluttered desk somewhere, I'll be sure to try this when/if I find it.
