Greetings to all MB03+ fans!
Probably the most common introductory question we got was "What is the EXTRA button for?".
It is now clear that this will be a button that can show a lot of what is happening in your ZX Spectrum and also in the MB03+ connected to it.
This functionality started with the character mode and bars of AY/YM-chips and the GeneralSound soundcard channels,
continued with displaying gigascreen effects and finally settings in the setup reached the maps of ports and memory segments.
Currently there are three so-called "LED-maps" in the MB03+.
Two maps show 1KB areas where the CPU is running and where the CPU is reading and writing from/to memory.
The third map shows the internal processes of the Spectrum (or the Pentagon with 512KB RAM!), incl. divide and flash memory settings.
Please see details in the Hood's technical description
or in the updated Quick start
Your TeamMB03+
