The TRS-80 was one of the 3 vintage computers I cut my programming teeth on, third in line behind the Atari and the Apple ][.
First generation Color Computer in original silver and later white case. A Different Kind of TRS-80 Although it shared TRS-80 as part of its name with, the Color Computer was an entirely different machine. The original TRS-80 line was built around the Zilog Z-80 CPU, while the Color Computer used the CPU. That means no software was compatible between the two lines. Color and Home Computing The, a single-board computer introduced in 1976, was the first model to support a color display, and the, released in 1977, was the first fully assembled computer with a color display. In 1978, Atari released its first personal computers.
Befitting its history in video gaming, the had color support. Texas Instruments joined the home computer market with its 99/4A in 1979 – it even included its own 13″ color monitor. Jumped on color in 1980, when it released the VIC-20, the same year that Tandy introduced the first TRS-80 Color Computer. Origin of the Color Computer Radio Shack teamed up with Motorola in 1977 to create a lower-cost home computer.
The first product was a home terminal that could be used with an ordinary color TV, eliminating the cost of a computer monitor. Motorola sold it as the AgVision terminal, while Radio Shack called it the VideoTex Terminal (right). Fans of the Color Computer will immediately see the origin of its case. The VideoTex Terminal used a 6809 CPU, 6883 Synchronous Address Multiplexer, and 6847 Video Display Generator, all from Motorola.
On July 31, 1980, Radio Shack delivered the TRS-80 Color Computer, essentially a VideoTex Terminal minus its modem but with a cartridge slot, I/O ports, and joysticks. That model had 4 KB of memory and 8 KB of ROM that included Microsoft BASIC, which Tandy called Color BASIC. The new computer retailed for $399 at Radio Shack stores across the US and Canada. The friendly little computer soon acquired the nickname CoCo, for Color Computer. As with the older TRS-80 line, there were different levels of BASIC for CoCo.
Color BASIC was the core language, and Extended Color BASIC was a more powerful version of the language. Quickbooks for mac. When the Color Computer got a floppy drive, Disk Extended Color BASIC arrived, and the final iteration was Super Extended BASIC for the CoCo3 – but we’re getting ahead of ourselves. CoCo was meant to connect to your color TV, and it used program cartridges like Atari home computers and game consoles.
CoCo 1 The original Color Computer used the same chiclet style keyboard as the VideoTex Terminal and the same 0.895 MHz 6809 CPU. (I believe this was the only home computer to run at less than 1 MHz, although not by much.) Although there was a 4 KB version, you needed at least the 16 KB version to use Color BASIC, which was included with the 16 KB and 32 KB machines. A 64 KB model was later added and the 4 KB and 32 KB versions were phased out. Extended Color BASIC was a $99 upgrade. Later on, CoCo got a full-stroke keyboard and came in a white case, replacing the silver of the original. TRS-80 MC-10 In 1983, Tandy introduced a smaller, lower cost version of the Color Computer, the TRS-80 MC-10, to compete with the Commodore VIC-20 and Sinclair ZX81. Unfortunately, the MC-10 was crippled to prevent it from competing with the full sized Color Computer.
