I would like to know the timing of /uds, /rom_select and
address valid on the st's rom port,  can anyone help ?.  Also
is it possible to read from the rom port using pc-speed ?,  and
finally what is the sm124 hardware hack that enables the
pc-speed to do 'hyper' hercules emulation,  and has anyone got
the hercules mode to work with graphics in quick-basic 4?.
(The pc-speed disk refers to the hack,  but the UK distributors
apparently have not yet been told what it is).  Any help
appreciated,
