True, I thought I mentioned the color thing, but I guess not. You definitely could not read a TRS-80 clearly on a TV. You could on an Apple, but who would? Most people - remember the buyers were predominantly hobbyists and schools - bought the monitors.
I was working on a TRS-80 Model I in the late 70s, I want to say 1977 but maybe it was '78. I remember it vividly, even down to the massive 4kb memory expansion (which weighed around 10lbs and threw off massive amounts of heat).
Later on we got a Model III. It didn't have nearly as much character as the I. I didn't like the monolithic looks of it much but it was admittedly a much cleaner machine with the built-in disk drives (the Model I eventually supported 5 1/4" floppies but they were humongous standalone units.)
What fun!
