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

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 !

  1. Great site. Loved my MZ80A which is still in my Dad’s loft somewhere.


    • Thanks for commenting. Hope your MZ still works, it’s a great machine. If you ever need any tapes then contact me. On that note : Do you have any tapes yourself that you’d like archiving onto this site?


  2. Thanks for uploading my games Cursed Chambers and Quest and Alien Attack to youtube!! I wrote them when I was 16 and just showed them to my 13 year old son!
