Picotron Memory Layout
Overview
Picotron has 16MB of addressable RAM (0x000000..0xffffff), that can be manipulated using standard memory functions ( poke, memset etc).
Most of the values at the following special addresses can be manipulated using API functions (e.g.pal() writes values to the colour tables), but they can also be manipulated directly in memory for greater control.
