I was contacted a few weeks ago with regards to dumping a PAL from a Namco PCB. The PAL is labelled SYS2V-2.
The chip arrived yesterday from Italy and it turned out to be the most difficult PAL16L8 to dump yet.
The output from the ABI was fairly unusable as it produced FAR too many product terms for some of the pins and would not compile.
Most of the pins were fairly easy to figure out from the listing but pin 12 was a little bit crazy. After a night with the logic analyser hooked up to it I had something that was almost the same in my simulation as what the real chip did. There was one state that did not match up but I emailed the .JED files anyway to see if I was anywhere near. Well so far so good as 2 of the games it was tested on seem to work now.
Although I cant test this myself Im hopeful its OK and its on my download list now.

MrDo has sent me the equations for the PLDs at 7C and 2N.
I already had the ones at 7C but his equations can be seen in the comments to the first Pole Position PAL dump post.
The second dump from 2N I did not have and I have compiled it using WinCUPL.
I dont have a PP board to test this but MrDo has confirmed it working so will be marking it as Tested.

Thanks MrDo

I recently offered to help a fellow UKVAC member out with recreating a 82S153 in a GAL16V8.
We were originally hoping to get a dump of the original chip and convert it over but we were sent a Verilog implementation.
After a couple of attempt we finally got it working and it is now available for download.

The GAL in question replaces the PLD at 7C, connected to the sound Z80 CPU.
Massive thanks to Adam over at http://ppclone.blogspot.com/ for providing his code.

Got a mates MTX512 here and noticed it has a PAL so would have been rude not to dump it.
There is the PLD listing for this PAL available somewhere on the net but not an actual JEDEC file for it.
GAL has been tested and confirmed working

Today I added 4 new PAL dumps.
The first 3 are from a CPS2 motherboard and are labelled as follows:
BGS-A2
BGS-A3
BGS-A4

These were taken from a non working motherboard and dumped using the ABI. They are untested at this point as Im not removing the pals from a known good motherboard to test so if you use these please let me know if they work or not.

The next one is something Ive been working on for a while and have put quite a lot of effort into.
It from a Sega ST-V motherboard and is labelled 315-5833.
Again, I am marking this as untested. I have tested it successfully with my 3 games which are Die Hard Arcade, Winter Heat and VF Kids. It also works with the Modbios.

Please test this one out as much as you can and let me know how it works.
Im pretty sure that it wont work with any add-on hardware but im also sure that all of that stuff came with a replacement GAL.

Today I found a PLS153 and a couple of PAL16L8 IC’s on my old Mortal Kombat board.
I have added the original PLS153 dump and also reworked it to work with my GAL adapter, both are in the Downloads section.

The 2 PALs were protected so these were dumped with the Boardmaster.

If any of these IC’s are missing from the board, it will not boot at all.

The manual for MK states the following for the chips:
5346-40025-2 => PLD Address Decode
5346-40025-3 => PLD Video RAM Control
5346-40025-4 => PLD Local Control

These have all been tested

Dumped a PAL16L8 from the Pocket Gal bootleg board I got.
The PAL was unprotected and I have converted it for use on a GAL16V8.
This has been tested working.

UPDATE: When I get an idea in my head the tendency is to get it done or ill think about it constantly so the second and final PAL on the board is now dumped and converted to GAL. The original device is a PAL16R6 and this was also unprotected.

A guy has called Zabanitu has contacted me with a PAL dump from with bootleg Commando board, he has also made a nice little schematic of how it connects up.
Many thanks to him for this.

I dumped the 4 PAL16L8s from Op Wolf this morning.
I haven’t yet had this board up and running so these are untested. If someone could verify these for me I would be most grateful.

EDIT: Tested these now and they seem to work fine
They are:
B20-09.IC19
B20-10.IC84
B20-11.IC85
B20-12.IC92
