So that's for using other MCU's, is emulate other ones ?? I figured it was going to be computer software emulation, but yeah a PCB and a few parts can do it...
I just downloaded a few CPU/MCU emulators, like one for the Z80. I need to read a pile just to get anywhere in the program tho. I want to find a simple 4 or 8-bit MCU emulator, with just some buttons and lights, and opcodes.
