Ok in this short time I've now successfully booted the apple II+ rom and
can program in basic, with a few issues currently i need a keymap for the
keyboard (e.g. which key is which keycode) and some sample basic programs :)
then i've just got to finish the slotmanager and a disk controller
(shouldn't be too hard)

Simple enough: the value to stuff in $C000 is the ASCII value of the key OR 128, and when $C010 is read, the value of $C000 is ANDed with 127.
