Yes, use the Time Manager rather than write to the VIA directly, I
suppose.  I forgot about the Time Manager because I was around when they
wrote the Time Manager and I remember all the problems that early
versions had... and then they fixed them all and now it works great.
But for some reason I still remembered its beginnings back in the
"halcyon days" of the Mac Plus in late 1985 and thought "write to the
VIA yourself".  Actually, when I talk about writing directly to the VIA
I do not mean hard code an address, which is what everyone gets all
excited about when they talk about writing directly to hardware.  That
is just plain stupid.  What I mean is, get the low-memory global pointer
which points to where the VIA lives and then use the chip, which works
fine on all of our computers.  The only other problem, however, is that
some machines use more of the VIA than do others, so the Time Manager
really is the best way in the end.  End of historic-melancholic look at
the past.
