PAL chips available for upgrade

[Kevin O'Gorman]

I have finally found a source for PAL chips for the upgrade to the UNIX PC.
Correctly installing one of these babies makes your system (7300 or 3b1)
able to fully control a hard disk with more than 8 heads (up to 16 heads).

I did this modification myself about 2 weeks ago, and I am quite happy
with the added disk space.  You can do it yourself if you can disassemble
your UNIX PC, have a soldering iron, a desoldering tool of some kind,
some patience and a lot of care.

Assuming that there will be some interest in this, I have ordered some of
the required materials, and will make them available by mail.  The main
thing you will get is a programmed PAL, ready for installation, and the
installation instructions I used for my upgrade.  I will make this
available to all interested parties for $40.00 each.  I will make a 30-day
(or whatever longer period seems reasonable to me) warranty on the parts
I supply -- you have to take responsibility for the modification.  Details
on request.

I expect to have the PALs programmed by August 15.  I can begin shipping
as soon as that happens.
