If it is indeed the JTAG MK1 as I suspect you can use: "Supported Devices Currently the JTAGICE supports the following devices: ATmega16(L), ATmega162(L), ATmega169(L or V), ATmega32(L), ATmega323(L), ATmega64(L), ATmega128(L)." and I think one of the CAN chips. It's all there in the Help files in AVR Studio version 4.xxx I don't believe AS5 supports the old ICE but don't really know.
