Another lowest cost 8-bit computer from the early 80s. This one is a MC-10 or better known as the Tandy Micro Color Computer. It used a Motorola 6803 processor and had a whopping 4K. It was the little brother to the Tandy Color Computer. While better in many aspects than the Timex Sinclair, it came out a bit later and never sold near as well. Featured include the 4KB of main RAM, a serial port, color graphics, cassette report, a keyboard with actual keys and a 16 KB expansion option. It had its own video chip (Motorola MC6847) and ran at 0.89 MHz. So probably a better deal than the Timex Sinclair which actually had to use CPU cycles to draw the screen.
This one was given to me by a coworker after he found out I collect odd computers. It appears to work. The display on the LCD TV is not so crisp.
