EEPROM Test



I know it looks like a mess, and it is, but this test of the 74LS193 counters driving an eeprom was a success. The counters and eeprom are located on the breadboards, the left display is showing the current address (the output of the 74LS193 counters), and the right display is showing the stored value in the "A" register. Because the "A" register is latching with the clock, it always contains the output of the eeprom (the eeprom writes to the data bus, and the "A" register is reading from it).
