Supposedly, it is possilbe to swap the Western Digital controler
chip which is limited to 1024 cylinders for a newer WD chip that
handles up to 2048 cylinders.  I don't know if this requires
cutting traces and adding jumpers.  Dealing with more than 8 heads
would require doing some metalwork on the motherboard most likely,
I am told.  Supposedly the two WD controllers are code-compatible,
thus all that is necessary after the hardware kludge has been done
is to go back to the diagnostics disk and reformat/repartition the
drive :-), the "all this is necessary" being tongue-in-cheek.

If anybody pulls off adding a big drive, I'd be interested in
hearing how its done too.
