Summary: ATT MS-DOS integral clock support


One good reason to use [MS] DOS from AT&T is that it has internal
support for the 63xx's interanl battery backed clock.  If you
insist on using generic MS-DOS, there have been several postings of
"setclock" that read the hardware clock and reprogram the 8253
timer chip t.o.d. interrupts to PeeCee compatible rates. If you
insist, I could email you a copy of setclock if you can't find it
in your system's news archives.  We tested setclock on a system
using a DOS 3.2 intended for Eposn brand computers.  Setclock
allowed the Epson DOS to apparently function correctly on the 6300.

Note that there are reports of supposed subtle bugs in generic
MS-DOS 3.2 floating around.  One would assume that AT&T has cleaned
up the port to be sufficiently well behaved on their hardware.
