Can you share a link? Do you think would it be possible to play with the code from the (free) book "Machine code for beginners" [0] with that emulator? I'd like to get some familiarity with machine code, and thought maybe it's a simplest way to start with. Or maybe you can give other suggestions for the emulator?

From the book (page 3):

> The book is specially written for computers with a Z80 or 6502 microprocessor.
