TRS-80 Color Computer

On July 31, 1980, Tandy announced the TRS-80 Color Computer, which shares the same case, keyboard, and layout as the AgVision/VideoTex terminals. The internal modem was removed, and I/O ports for cassette storage, serial I/O, and joysticks were provided. An expansion connector was added to the right side of the case for future enhancements and ROM cartridges ("Program Paks").

Here you can see a later model, the Color Computer 2, along side the Micro Color Computer, and the Dragon 32, a TRS-80 CoCo clone from the UK. Each system in the CoCo family had some method to get online.

The Color Computer supported "ROM PAKs", including the Videotex Cartridge. This effectively turned the CoCo back into an information terminal, if the user had a paid account for the desired services such as CompuServe.
