Time passes, and software continues its evolution.
So even z80cpu.eu has started to run in a new environment: php7, fpm, and so on, which made mandatory the transition from version 2 to 3 of its CMS: Joomla.
I'm slowly fixing some small bugs due to the passage, but overall the site should no longer suffer of the past weeks malfunctions.

The king is dead, long live the king!
