Bill, I beg to differ. One of the features of the 68901 is the ability to
program the individual sections/functions independent of the others. True some
of the timers are critical to video timing; but the serial portion with its
individual interrupts and registers could and should be handled by the OSK
device driver. The current driver does this by using TOS ROM calls; there-in
lies its deficiency. A properly written driver should never touch the TOS ROM
calls or any of the critical functions of the chip. I am currently working on a
keyboard/multiple screen driver that will be independent of the ROMs. It WILL
use some of the 68901, including one of the timers. The ke point is one must
understand the whole of the system to break out the parts. After I have
finished  I hope to get to the STSIO driver. I have
not yet run across the caveats you mention, but would appreciate any
information you have.
