This is a continuation of my video series on the Heathkit ET-3400 series of trainers. I manage to get a nice ET-3400-A and I compare it to the original ET-3400. I also demonstrate the cassette interface of the ETA-3400 memory/io accessory clone that I built last video. I wire up one of the experiments from the manual, an ADC connected to a 6821 PIA. For more electronics projects, see smbaker.com
