In order to protect your electronical devices, always turn off your ATARI before inserting or removing cartridges.

ALWAYS TURN YOUR ATARI OFF BEFORE CHANGING/SWITHING BETWEEN DIFFERENT ROMS!

If your programmer have capability to test IC chips, like 74LS series, then you should not forget to test them before soldering, some chips may have defect. (TL866 Minipro Programmer is able to test some of logic IC)
