Looking for P5.1 PALs

[Paul Homchick]

The effort of keeping my system from running out of disk space, and
constantly running at five percent free has finally gotten to me.
So, I have taken to collecting hardware.  I have a 3B1, a WD 2010
controller chip, a Maxtor XT2190 drive ($1200 for a factory refurb;
if anyone is interested in the source, let me know), and the P5.1
field upgrade *instructions*.  What I don't have is the new PAL, or
a way to burn it myself.  Does anyone know of a reasonable source for
these chips, or of an alternative hardware modification to allow the
use of >8 heads?  Thoughts of an extra 80 Meg of disk space, just out
of reach, are keeping me awake at night!
