Hi Folks,
	since a bunch of you now have pc532 pcbs, and have to hunt up
components etc, I assume some of you would like the pal files in jedec
format.  Especially for those that don't have CUPL or TangoPLD. The
following shell archive has the following files:

	dec32.jed	15ns speed
	dramc.jed	10ns
	dramen.jed	10ns
	wait.jed	15ns
	scsi.jed	15ns
	parity.jed	15ns

The jedec files also contain test vectors which will enable you to have some
confidence with the programmed pals. I recommend that you use GAL16V8A-15
Gals from either Lattice, AMD or National Semi, since they draw less power,
will give 100% yield (pals don't always program correctly since they rely on
blowing fuses) and are a bit faster than the equivalent PALS.  Note: the
DRAMC and DRAMEN devices are 10ns, so you must either use PAL16R8D and
PAL20L8D or GAL16V8A-10 and GAL20V8A-10 respectively (I think Lattice is the
only manufacturer that currently has 10ns devices). If you use a PAL for the
DRAMC (PAL16R8D), try not to get AMD parts, the MMI (also from AMD) version
is more recommended. Both will work equally well, but the AMD version does
not support register preload for testing.

Note that the jedec files contain some control codes (such as ^B), so they
have been btoa-ed.
