The Tandy Color Computer was introduced in 1980 and was followed by the Tandy Color Computer 2 in 1984. The original price of the Color Computer (or CoCo, as they are often called) was $300 in 1983 (Consumer Reports, p.475).
Processor: The Tandy Color Computer uses a Motorola 6809 microprocessor which is capable of addressing 64K of RAM.
RAM: The Color Computer originally came with 4K of RAM with later models featuring more memory. The memory could be upgraded to a total of 64K.
Keyboard: The Color Computer uses a simple calculator style keyboard with 53 keys (Consumer Reports, p.475). The Color Computer 2 came with a typewriter style keyboard, but has the same key layout as the original Color Computer. The keyboard has all standard ASCII key except 96 and 123 though 127 (`, {, |, }, ~, del). Other characters come from 4 arrow keys or other keys combined with the shift. There is no control key, so control characters can not be typed either.
Video: The Color Computer's video output is radio frequency, so only a TV set can be used for a display. The display supports 32 column by 16 line text, which makes applications like word processing and spreadsheets difficult.
Storage: The Color Computer has a cassette interface connector to connect with a standard portable cassette recorder. The Color Computer has an optional floppy disk controller that connects to the cartridge port on the side of the machine. The controller uses industry standard drives, so any size media can be used. The Color Computer's operating system is stored in the disk controller's ROM, and the capacity is hard coded.
