All these use an Elf with VDU (MC6847) video chip. The mode of the chip is not set by an OUT instruction but instead set by writing to address FFxx and bit 6/7 in video memory. As far as I have figured out from the manual and code A/S is linked to bit 6 and INV to bit 7 of video memory. CSS bit 1, INT/EXT bit 2, A/G bit 4, GM0-GM2 bit 5 to 7 of address FFxx. Two configurations are provided VDU / Ascii keyboard and VDU / Hex keypad, first for Tiny basic and Monitor, second for the games.
