Hooking Up the CoCo 1 & 2

The CoCo 2 is very similar to the original TRS-80 Color Computer in its capabilities. Most significantly for this section, they have the same connections to the outside world.

What's in the Case?

The CoCo 1 & 2 are pretty simple computers as shipped. Inside they have a Motorola 6809E microprocessor, 4 - 64K of dynamic RAM, and a built-in keyboard. On the right side is the expansion slot, where you can plug in Program PAKs (cartridges housing a program in a ROM chip), disk controllers, and other hardware expansions. On the back are DIN sockets for the serial port (often referred to as the "bit-banger"), the cassette port, and two joystick interfaces. There is also an RCA jack for the RF modulated audio/video output.
