On Apple, Apricot and other computers Roberto created the software for astrological calculations. He created his own key codes to compact his programs. He used O and 0, l and 1 as labels as part of the safeguarding against abuse by others. In short: he studied what he did and knew what he was doing.
He wrote the programs Ur and Urris, later AstroDivine. (All operate under DOS.)
Each of these convey his insights, for example: the HyperMandala is integrated into AstroDivine.
These programs may be described in more detail later.
