As the MZ 80B, the MZ 80A uses an expansion unit connected directly on the motherboard. It offers four slots for interface cards.\
Two of them are used on the photo : a Centronics interface card on the left and a Floppy disk interface on the right.

text: I quite agree, this was my second computer (ZX 80 was my first) and I loved it to bits. BASIC and PASCAL where my favourite languages I used to program with at the time. This was a very robust and well made computer with an excellent instruction manual. In the manual was a full assembler print out out of the operating system and this was how I learned to code in assembler.

Hi, I''ve got one to sell. I''m not sure if it''s in working order because I''m no expert (it wasn''t even mine) so any price starting from 120 GBP + shipping costs would be ok to me. If anyone''s interested, contact me.\

My first computer.
This was a lovely computer, and I'm thrilled to have one again.\
Currently working on a PCG and re-writing/improving the games i wrote back in the early 80s.
The Sharp User's Club by the way is a thoroughly excellent organisation and well worth contacting by anyone still interested in the Z80 Sharps

The Sharp MZ 80A was the "enhanced" version of the [Sharp MZ 80K](/museum/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](/museum/sharp-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](/museum/sharp-mz-700/). It was sold in Japan under the name **SHARP MZ 1200**.
