Cracking open the Radio Shack TRS-80 CoCo

The Radio Shack TRS-80 Color Computer – or CoCo – was one of the first colour home computers, and various models sold well in the US from 1980 to 1990. It didn't make much headway in the UK, although it inspired a largely compatible clone, the Dragon 32.

Original CoCos had no lower-case letters, a crude keyboard, little memory and could display only nine colours at once. The model pictured is a Color Computer 2, from the mid 1980s.
