AtomBusMon - ICE-T65 / ICE-T80 / ICE-6809

HardwareAtomBusMon - is an open-source In-Circuit Emulator for the 6502, 65C02, Z80, 6809 and 6809E 8-bit processors.

It is built using an off-the-shelf programmable hardware device called a GODIL that can be purchased for just over $50. The device plugs into your CPU socket, replacing the CPU, and you can control it over a serial connection to debug your software or hardware.

You unplug the 6502 processor (which is in a 40 pin DIP socket) and plug in the GODIL loaded with ICE-T65 design. ICE-T65 contains a fully functional 6502 processor, plus a second arduino compatible processor running an interactive debugger application via an independent serial port.

Now you have a set of powerful debugging tools at your disposal:

  • You can run memory tests on the host RAM
  • You can compute CRCs over the hosts ROM (and compare these with values from known good ROMs)
  • You can peek or poke host I/O devices, or host memory, or even the screen
  • You can set break points on certain pieces of code being executed, or certain memory locations being accessed
  • You can disassemble bits of the host memory, do memory dumps, etc.
  • You can reset the 6502 processor and single step through the operating system as it initialize
  • You can even inspect the 6502 processor registers while it is stopped
Very useful if you need it.

It looks like this Spartan 6 XC6SLX9 board is supported too, with a level converter board. Check this (very long) thread.
