PiStorm Tester is a PCB that exposes all the IO's of the 68000 DIP64 socket that PiStorm uses. There are status LED's on all the control/Address/Data Bus lines to easily see if a single line is stuck high or low. each IO is also broken out to a header for easy connection to an external microcontroller such as an arduino for more accurate analysis of the outputs, or for pulling inputs high or low as required. where the line is either an input or bi-directional (such as the Data bus) the headers have a handy VCC and GND rail adjacent for easy jumpering. Combined with testing programs on the pi such as buptest, it becomes easy to narrw down individual faults such as unsoldered or broken individual flip-flops.
