Testing the Unknown

Not what I wanted to see:

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
 
Looks like my backup chip really is not an Arduino.
Neither are the chips in the new order.
 
I took a known good circuit with a known good Arduino in it, removed the Arduino and replaced it with an unmarked chip. I recompiled the code and tried to download it. I received the error above. I powered down, swapped the known good chip back in, powered up, recompiled, loaded to the chip and the program ran as expected.
 
Time to contact Sparkfun.
