My first computer was a Tandy Radio Shack Color Computer I with a whopping 16 KB of RAM, the BASIC language built into the ROM, and an optional ($$$) cassette tape recorder for storage. You booted this thing, and the screen above is what you got. To a 17 year old science and math geek, it was the coolest thing on Earth, and I was absolutely hooked. I still have this computer, sitting on a shelf in my office, and I will never part with it. Here is the The Java CoCo Emulator.
