TRS-80 MC-10 Micro Color Computer
The MC-10 was the semi-compatible cousin to the Color Computer 1 & 2. It
was just a little larger than the Sinclair ZX-81 and used a similar style
external RAM expansion. The base machine shipped with 4k of RAM and there
was an external 16k RAM expansion pack available for it. Also like the
various Sinclair machines, it had a chicklet keyboard with keys small enough
to make touch-typing virtually impossible. Unlike the Color Computer 1 & 2,
the MC-10 used a Motorolla 6803 as it's CPU and had provisions on the rear
for plugging in an A/C power supply, a mini-DIN serial port connector, a
connector for an audio cassette for storage, and an RCA jack for video from
it's RF modulator. The cassette interface cable is the same as that used
by the other Color Computer models from Tandy, while the power supply is
quite odd, providing 8V AC input to the computer at 1.5A.
The MC-10 was released in 1983 and proved quite underpowered for it's
intended market. It is considerably less well known than the other members
of the TRS-80/Tandy Color Computer lineup and there was little software
released for the machine. There was a small thermal printer released for
use with it though.
