NUOVA ELETTRONICA
Z80 COMPUTER
This site is dedicated to the computer published in kit by Nuova Elettronica italian magazine from 1979 to 1985.
Here you will find all articles and informations I found related to this computer, schematics, software, and add-on cards made by me.
Now this kit is obsolete, but it's very interesting for technical solutions used, and also because it was helpful in teaching alot of technicians that, like me, spent many hours in assembling and programming this beautiful computer.
I'm always searching for informations, hardware, software, third party add-ons and everything else related to this computer: if you have any information or question don't hesitate to email me.
A particular thank you goes to Nuova Elettronica magazine that gave me permission to make this site.
NOTE: unfortunately Nuova Elettronica ceased publications with number 250 on September-October 2012, and on 14 November 2013 a bankruptcy procedure against C.R.E. (Centro Ricerche Elettroniche) that owned editorial rights was started (source Wikipedia).
