My name is Roland MacDonald, my friends call me Mac I am a retired but not bored engineer My great joy is my workshop, a two car garage with heat and air. I am a private pilot with 1800 hours flying time I have built four Kit planes and restored two Cessna aircraft My last contact with electronics was in the vacuum tube world. I am really enjoying the new transistor world.
