@ -14,14 +14,12 @@ mc8030: very little info available. The area from FFD8-FFFF is meant for
interrupt vectors and so on, but most of it is zeroes. Appears the keyboard
is an ascii keyboard with built-in beeper. It communicates via the SIO.
The asp ctc needs at least 2 triggers. The purpose of the zve pio is unknown.
The system uses interrupts for various things, but none of that is working.
Looks like maybe a sio bug is preventing the keyboard from working.
