PJ5 - 02 -Testing the Test Tool

Running tests on our test tool for our TTL CPU project. Very simple little board with a few DS1417 (TIL311) displays, some LEDs and a couple of banks of switches. Here you can see we've put register "1" onto databus A and Register "0" on databus B and we've got these connected to a pair of the displays. The jumper switches allow us to choose which register goes to where. More details on our blog - https://pj5cpu.wordpress.com/
