The SC/MP has
some I/O lines on the chip. IIRC there are 3 flag outputs
(on/off signals controlled by bits in the CPU status register), 2 sense
inputs (which can be read as bits in the CPU status register, one can
also be used as an interrupt line), and serial I/O lines which go to the
'ends' of the CPU extenstion register (which can be shifted under program
control). These lines _are_ brought out to the connector at the back.
But the CPU buses aren't.
Ah, the useful stuff, then :o|
