Demo of Multi-SLOT 1200XL with TKII-PB1200 board installed

The TKII-PB1200 is a Pokey Piggyback board that allows bank selection of multiple OS and Language SLOTs to be done via the stock or optional PS/2 keyboard. There are two possible 16K OS versions, and four possible 8K Languages that are completely selectable via keyboard control. The system executes a Cold Restart when a new selection is made, so there is no need to power cycle the unit. On board EEPROM backs up the last selection and will restore it the next time the unit is turned on.
