(TL;DR) I have three z80 processors and no know-how. I need help getting a working circuit/program. I have a z80 processor (actually I have three) that I want to do something--anything--with, even if it is flashing an LED. Okay, I already did flash a few LEDs using a basic test circuit I found online, but I want to actually program the flashing. I already have what I need to build a system (RAM, ROM, Arduino Uno that I can sorta turn into a programmer). I found schematics for wiring it all together and they seem rather straightforward. But that's about where my knowledge ends. I have looked and looked and looked, but have yet to find a single project that uses very minimal parts and programming, outside of the basic test circuit. I came across a few posts of people saying they have built small projects like that but didn't have schematics or the program or anything. As stated before, I don't care if I flash an LED (I literally looked that up and found nothing). I just want to have something I can say, "hey, look at what I did, bitches." [Edit] Do I program the processor itself or the ROM or both? That's a question I need answered too.
