SGS-ATES NBZ80 Nanocomputer, 2650 Mini Computer, Ohio Scientific OSI 560-Z

Searching for Intersil, I found an OSI board compatible with both Z80 and 6100 (12 bit). There’s also a video

Then I found this site with 2 posts about OSI Challenger 1P

He also has a 2650 Mini Computer

And last not least a 1979 Italian Z80 trainer but missing the golden caseing. There’s also a NBZ80-S. Breadboard and remote controller

Better pic and info here (in German)
