AT&T 6300 Battery backed-up clock interrupts?

[Douglas F. DeJulio]

You can grab a little program off of simtel20 that'll set the DOS
clock from the hardware clock.  There are two directories that'll be
of help, pd1:<pc-blue.vol242> which is all AT&T 6300 stuff, and
pd1:<msdos.compatibles>, which has a copy of the clock setting program
if you don't want to wade through all of volume 242.
