In 1979, the NEC PC-8001 was an excellent machine, offering 8 colors when most of its competitors were still monochrome. There is even a (low) graphic resolution of 160 x 100 dots. It could display capital and small letters.

The PC-8001 had great success with Japanese businesses, where it was widely used. At the time, NEC claimed that the PC-8001 represented at least 45% of their home japanese market. This is when the PC serie from NEC and MZ serie from Sharp started competing!

The base system was 32K, but a company in Concord, CA. made a thing called the "WEDGE" that mounted below the Base system and added the needed 32K plus it had analog and digital input ports and other goodies.

The US version of the PC-8001 was named PC-8001A.
