Greetings. It seems that the PAL-programmer thread has died. I
don't like that one bit. Why? Because nothing got accomplished.
Anyone know of a cheap PAL-burner? Anyone know of free/cheap
software to drive it? Anyone know of free/cheap software to
minimize the equations? We ALL know that there is NO software
that will drive ALL types of PALs. We ALL know that not all
makers of PALs make this info avaliable. We ALL know that
there will be no simple solution.
FINE.
I want to know of a SPECIFIC programmer to program a SPECIFIC
PAL that is driven by BRAINDEAD software and that all the above
can be afforded by a college student! (ie. $0-$300 :-)
There. I hope that's specific.
WHAT I HAVE:
o Flowchart of PALASM.
o FORTRAN IV (G) source of PALASM for series 20 and 24 of Mono-
lithic Memories. By: John Birkmer and Vincent Coli.
Series 20 - 1,662 lines | Series 24 - 1,527 lines (text)
(Source: Mational databook @ 1983)
o PLA compiler in FORTH (text form). "Modified version of the
paper by the same name which appeared in the 1982 FORML
Conference proceedings, pages 257-265, 6-8 October 1982.
Avaliable from the FORTH Interest Group, P.O. Box 1105,
San Carlos, CA 94070..." (3 pages of program)
o Blurb for "CUPL(tm) - The Universal Compiler for Programmable
Logic" Features:
- CUPL supports products from every manufacturer.
- CUPL has a PALASM to CUPL translator
- CUPL produces JEDEC output files.
Anyone hear of the above? How much? How good? Exists?
o Video Frame Grabber (composite in - > digital out) using
3 PALs (64R32, 16R8, and 20RA10) + Pascal source.
Please post replies - others want to know!
Take care.
Joke: I have an "elderly" (1985'ish) PAL handbook from some
company which has, as an application, a shematic for a simple
PAL burner. The application, naturaly, uses PALs. Catch 22.

Did you hear? Some Poles burned the Russian flag near the Soviet embassy,
in Poland. :-) :-) "Nothing is impossible if you don't have to do it yourself."
JDR Microsystems sells a PAL/GAL blower for somewhere around the $300 mark.
It uses a PC card (that can also be used to interface to an EPROM blower
and other similar things). I've got the EPROM blower and software, and I'm
considering buying the PAL/GAL blower, since I like the EPROM part.
It takes JEDEC files as input, I believe. I was going to use PLAN II from
Nat Semi to produce the file (I think it's free if you ask them for it).
It doesn't minimise the terms, but it does produce JEDEC files.
Hope this helps (even though my grammer is dreadful.)

If someone were in the business of making a cheap 'PAL' type programmer,
I would suggest designing something that handled (just) 'GALs' - the
EEPROM generic PALs. That would be a good compromise, especially as
the builder of a cheap programmer is probably doing cheap development,
and would appreciate the chance to reuse devices (which is possible
with GALs, but not PALs). GALs emulate most PALs.

I called National early this week, and they sent out their little
demo program "Opal, Jr." for the asking. Guess the name got changed.
It will do a variety (~12) of common PALs and GALs; runs on IBM PCs.
The program you use is called EQN2JED; it takes logic equations and
writes JEDEC files.
I'm a little suspicious of their 20L10 entry, though. The log file shows
one pin as being an `enable' while the data sheets for the 20L10 show it
as a normal input.

In fact if you can program the GAL16V8 and the GAL20V8 you have
covered an awful lot of the available PALs (emulation-wise) -
this programmer sounds like a good deal.

At one time, Monolithic Memories was very nice about giving out copies
of PALASM. Even when they started charging for it, they were willing
to send out a copy for duplication and return. They might still be
cooperative about it.
Have you checked out the JDR programmers? They have a PAL programmer
that isn't all that expensive. I don't know if it can be driven by
PALASM.
