There was a review in December or January's  (88/89) Byte magazine about a
product called "Boomerang", I believe.  It was a small battery and circuit
board which are mounted inside the PC between the power supply and the
??? (disk drive?).  It has a RAM-resident driver program which detects
power loss and stores memory, etc to the hard disk.  Upon powerup, a simple
command will reload the driver and all that was in memory and put you
back right where you were when the power went off.  This command can be
put in an AUTOEXEC.BAT file so that you always return to where you were
the last time you used the PC.  They recommend a second piggyback battery
for ATs and those with extended memory.  Price was 200-300, if I recall.
Note that this isn't intended to let you run off of battery power, but it
will prevent data loss through accidental (or intentional) power loss.

I have no connection to this except as an interested reader.
