Paul Vick writes about an early experience with a legacy computer. He never owned a CoCo, but it inspired him to learn about them. Our family’s first computer was a 16K Coco. If Paul had gotten that computer, it came with a great book on learning Color Basic and Extended Color Basic. I spent hours and hours typing in code listings from those books and the Rainbow magazine.
Now, you can experience a CoCo through a web page (Java required).
