The Radio Shack/Tandy Corporation TRS-80 Color Computer (nicknamed CoCo) was released in 1980, with subsequent hardware updates in 1983, and 1986. Despite its TRS-80 heritage, the TRS-80 Color Computer differed greatly from its predecessor with the implementation of a Motorola 6890E, rather than a Zilog Z80 processor.
The more expensive Motorola processor set the TRS-80 Color Computer apart from the Apple II, Commodore, and Atari systems which were based on the MOS-6502 CPU. While lacking the graphics and sound capabilites of some of its competitors, the TRS-80 Color Computer succeeded in raw computing power.
Released for $399, the TRS-80 Color Computer saw wide distribution and availability in Radio Shack retail stores located across the United States and Canada. Version 2 of the system released in 1983 resulted in a newer, smaller power supply and case, along with enhanced video display graphics. The Color Computer 3, introduced in 1986, upped the stock RAM configuration to 128kB of RAM, revised the keyboard, and again improved the systems video capabilities.
A wide variety of external add-ons for the system were released in the form of expansion cartridges including an RS232 Program Pak which added a RS232 UART for serial communications, a "Speech & Sound Pak" which provided a speech synthesizer and sound generation chip, 300 baud modem pak, 80 column display adapters, and hard drive and floppy controllers.

An ORIGINAL Tandy/Radio Shack computer
This was one of those great machines that you could do multiple things with. It had a cart slot to play carts that was made by Tandy carts. You could use that same cart slot to install a disk reader so you could not only save stuff but also run other applications on the system. You could plug this device into any kind of monitor, whether it be a standard TV or a specially designed monitor for PC's. there were a lot of great carts that came out for this system. My personal favorite was Silpheed, one of great shooters that ever came out. Another great one was Thexder, an action platform shooter game where you are a robot and you have to battle your way out of buildings.
I actually still own my Tandy Color Computer II and still works. (A few keys stick because of come soda I spilled on it, but luckily still works perfectly, I can still code BASIC if I needed to. Sadly I lost the floppy installment on it and so I can't save any work, plus I don't have any more floppies, since they don't sell them anymore)
Keep in mind this was when Tandy/Radio Shack was it's own company before the Microsoft takeover in 2000.

They don't make computers as sturdy as these
First computer I've ever owned in my life. Was given to me by a friend who arrived from the US. I was like 13 when I got it. Owning a computer at that time was very difficult and very expensive. I guess the guy didn't know what to do with it because he readily gave it, no questions asked. Loaded only with BASIC, I have written thousands of code for my science projects on this machine back in highschool. Had made several trips to the library looking for reading materials on how to use it. Very nice piece of learning equipment. It survived me for more than 10 year until I bought a PC when I was in college. I still have it. It still turns on and loads BASIC but the keyboard is damaged beyond repair so no way to use it. It just gives me fond memories of how it shaped my career and my passion for computers ad everything on I.T.
