There is at least one driver that will mate the 6300 clock chip with generic
versions of DOS.  One that I have heard of (but have not used) is archived as
clock90s.zip on the AT&T support BBS (201-769-6397).  Another claim for this
driver is that it will keep correct time for 1992 and beyond when even the
AT&T versions of DOS will be at a loss for the right time.  The documentation
for this package has the technical explanations why this is all true.
