Can you try reflashing the controller before you remove the chip ?
This will satisfy our question of whether it is the code or the chip which is faulty.
Let me know if you need instructions. Roboflash and the original code are in my file area.

It does look like the ATmega is damaged. The JTAG and ISP are both disabled on the ATmega in my C3024, so no other way to access it.
You have the same problem with new CPU that the JTAG and ISP pins are used for other C3024 functions, so need to be disabled. I did not do this on my test C3024, and retain JTAG, but lose the 4 analog ports. I made an adapter cable from JTAG to 4 servo connectors, and also added an extra pin in the reset pad.
For a new ATmega, you will also need the bootloader code, since the C3024 code checks it is there, and won't run robobasic programs without it. Let me know if you want that too, or just disable the cC3024 ode which checks for the bootloader.
Anyway thanks for trying.
