Hi!
        Does anyone know, where to find plans & software for
       GAL programmer. What aboat such a circuit that can burn
       code to COP8780?
        These need to be low cost systems, free software, simple
       circuit board.

search for RGBPLD.ZIP thats the only available DIY programmer design
for GAL's (if you dont find it, I can upload to our ftp site)

We have(had) plans to do a low cost GAL programmer, partially work is
done (our software does read and erase Lattice GAL's) however we are
not ready to publish the desing at this point.

There is no DIY for COP ASFAIK, I know something about the algorihtms
and it could be done, but isnt, check out the COP starter Kit. that's
the cheapest alternative I think

       .. That«s kinda expensive.. To order a preprogrammer GAL from
       Alta Engineering..

       I found this guy called franz polzer. He has programmer to wich
       I don«t need to order any expensive pre-programmed parts..

       I thought so too. Just had to ask.
       Btw, where did you get the algorithms??
       I«ll propably take the easy way, and keep on using pics, but anyways..

I think Nuts & Volts had an article a year or maybe longer on a GAL
programmer can't seem to find it right now...anyone else remember this
one?

Hi Jiri,

The May 1992 issue of Elektor Electronics magazine had an article on an
inexpensive GAL programmer, and later had a followup article with a
modification for newer GALs(in particular the 22v10). The author's name is
M. Nosswitz.

Elektor is not very popular here in the States, but in Europe it is widely
available, you might be able to find back issues. There was a PC board
available.

By the way, note that while GALs are more easily programmed than PALs, they
still use way too much current (100mA).

The Lattice ispGAL22V10 can be programmed via the printer port, using
the development and download software on the (free) Lattice CDROM. See
their web site for details:

       http://www.latticesemi.com/

You'll probably need a buffered cable, but circuit details are provided,
or you can buy one from a Lattice distributor.

There is a software called PALASM  or MACHXL in http://www.amd.com
you can right PLD code in JEDEC format for GALs PALs and more.
Then you need any device programmer to burn it.Sorry I do not
Know enything about COP8780.

there is no need for buffers at all if your cable is not too long,
<= 1 meter

the problem is that ispLSI22V10 is so expensive comparing to what
it has inside that it makes the use not reasonable in most designs.
16V8 is dirt cheap .7 USD (1.09 DEM)
22V10 is still cheap at 1.5 (2.3 DEM) if I recall the prices correct

but ispLSI is way much more :(
ispLSI1016 offers more for the bucks as ispLSI22V10 and is also
in system programmable

Granted, the Lattice 22V10 is expensive, but if one only needs one or
two, it is much cheaper than the other options when the cost of the
programmer is taken into account. Also, the free Synario software on the
CDROM is much nicer than PALASM, IMHO.

Jiri,

 Actually, the Alta Eng programmer takes no pre-programmed gal, just a
couple of buffer chips.  You may want to take a closer look at their
package..

 Also, I have redesigned their board so it is single sided and only
takes three wires on top, much more hacker friendly than the original
double sided board..

Hi.


GALs are very nice for little fast functions, as
adr. decoders, counters ... For testing an ispLSI
is OK, but in a final product e GAL is the cheapest
solution...


I am also very interested in building a simple
and cheap GAL Programmer. It seems there are only
few free projects.

* The PALRGB needs an extra ISA PC Slot Card and
this makes it to complex. The DOC says, it can
handle only 16V8 and 20V8.

* The Elektor Projekt seems to be easy, but you
have to pay for the Software :-(
The software Item is not listed on the Price
list on the Elektor Server.

http://www.elektor.ac-net.de

* You can also take a look at this site:

http://www.paranoia.com/~filipg/HTML/LINK/F_pal_gal.html


The Problem is, GAL manifacturers don't public the
programming algorithms.

So my questions :


* Have sombody the Software for the ELEKTOR GAL programmer ?

* Is there a source for the programming Algorithms, so i
can modify my EPROM programmer or build an new GAL programmer
( with a PIC ! :-)



Thanks!
St.
