2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues.
2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)
CoCo 1 & 2
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.
