* This is based on 2001N PET technology, 40 column text/character graphics. It does not have the CRTC chip in later 12" monitor PETs.
** Most early PET software was designed for the normal/graphics keyboard (20 key keypad), so any titles which bypass the OS keyboard routines may not work correctly with the business keyboard (11 key keypad). It is possible to support a VIC20/C64 keyboard via an alternate ROM, but this is not recommended as some keys are missing or labelled differently.
