Building a memory tester for the ZX Spectrum

Building a memory tester for the ZX Spectrum from components. This tester can test the lower Spectrum RAM chips, the 4116’s, and also the upper memory chips, the 4164’s. It has a nifty display as well to give you the results of the test. This memory test kit was kindly donated to me by Steve Truman. Thanks Steve!
