Welcome to my comprehensive resource site for the Sharp MZ-80A. Over time I’m hoping this will grow into quite a large catalogue of programming tips, games reviews & videos, manuals and other interesting historical information regarding this early ’80s computer. If it’s MZ-80A related you will certainly be most likely to find it here. Enjoy and make sure to check out the news section for what’s been added recently to the site!
PLEASE NOTE : Some people have not noticed the menu bar at the top of the website and, I think, have only seen this page. Please remember to check the menu at the top of the screen which is where you’ll find all of the rest of the content of the site.
Released : 1982
ROM : 4K
RAM : 48K (as standard in Europe)
Video RAM : 2K
Display : 40 x 25 characters

Processor : Z80A @ 2Mhz
The ‘Pseudo Graphics mode’ was achieved simply through a set of characters towards the end of the MZ-80A’s in-built character set, as below:
As you will see when exploring the rest of my site, nowadays we can access a pixel via software if required. In truth, it is possible potentially to have the MZ-80A’s full resolution which is 320 x 200 !
Welcome to my site dedicated to the Sharp MZ-80A. Why does this site exist? Not only has there been very little information regarding this excellent old machine on the internet up to now, including how to program it in a way to push it further than it has been before but even back in the days when it was still being sold in shops there was precious little support from the magazines of the time despite software houses such as Kuma and Knights of Aberdeen producing a lot of programs for it. Most of the time it was the MZ-80K (which came out before the 80A) which got more attention. This you will notice in some of the archive material on this site. Luckily both machines are similar in a variety of ways.
On a personal level, the MZ-80A was my 2nd home computer after the Sinclair ZX-81. I loved it at the time for many reasons, especially the sudden jump up from 1K (expanded to 16K) found on the ZX-81 to an amazing 48K, the fact it was a ‘clean’ machine which meant when you switched it on all of the RAM was available for use immediately (all you had was the Monitor kernel, no programming languages : you had to load BASIC from cassette tape for instance) and also, as a child, I loved the sleek design of the MZ-80A, it made me feel like I was on-board the Liberator from Blake’s 7 (my favourite sci-fi program as a kid) !
Finally, another reason for this site’s existence is that there is a lot of inaccurate information out there on a lot of ‘old computer’ dedicated websites which needs correcting. I also want this site to not only be as accurate as possible but be as comprehensive as possible. I enjoy sites like Lemon64 and Gamebase64 which provide as complete an archive as they can. Hopefully this site can be similar for the Sharp MZ-80A.
So if you remember the old days of green screens, built-in monitors and “MONITOR SA-1510” then I hope you enjoy this site. Feel free to contact me via my Contact section.
One of the items bundled with the MZ-80A computer was the software pack. This included a manual describing how to use the various bits of software and four tapes containing different types of programs. These were the Games, Education, Home Finance and BASIC Tutorial tapes. Below you will be able to find not only a scanned copy (PDF) of the Software Manual but also links (click on the photos of the tapes) to full downloads of the software.
