I've already looked into that.  I have two hard drives on both my systems and
two devices on the second port adapter, so I would need a controller card and
some magic to produce an additional IRQ -- had to remove an ATA 66 controller
because I didn't have enough IRQs to use the machine with all the stuff 
connected.

Have also picked up a Trios unit, but not installed; it would permit having 
two or
three primary hard drives with different OSs, etc. and a common data 
drive.  Little
home office setups don't justify the stuff a real business would 
need.  Besides,
our principal risk out here is lightning, and when a computer is really 
fried, any
number of hard drives can be destroyed at once.  I've had fair success with 
power
protection, had one UPS fried, but computer lived. Had another motherboard 
fried
via telephone line, and a parallel port zapped due to crossed polarity of 
AC line at
different receptacles. Cities are better.

Worked for a time in a shop where the VAX cluster downstairs in the bunker was
optically isolated from the equipment at ground level.  Took a hit which 
fried the
stuff upstairs, including a couple of printers and a dozen dumb terminals. The
computers downstairs purred on, and the gas pipeline continued normally. One
line printer upstairs survived; it, too, was optically isolated.  That 
place went to
backup power one day a week, just to be sure it would work.

Choppy
