The Sharp MZ 80A was the "enhanced" version of the Sharp MZ 80K. It had about the same technical features but offered a typewriter keyboard, better display, enhanced text mode and a Parallel printer port.
Like the MZ 80K and the MZ 80B, it had no language in ROM. The disavantage was that user had to load a language from tape each time he switched the machine on, on the other hand, any language or machine code program could be loaded instead of the standard BASIC.
The MZ-80A was the last evolution of the all-in-one MZ-80 serie and the predecessor of the MZ 700 serie. It was sold in Japan under the name SHARP MZ 1200.
