This technical information has been gathered from a dissassembly of the ROM.
* Button triggers [[NMI]]
* 8K ROM data has 4 regions. There is an NMI vector at offsets &0066, &0866, &1066 and &1866 within the ROM data. This suggests each of the 4 regions is selectable and mappable into the range &0000-&7ff.
