Since I was working on an original Taito Liquid Kids PCB I took the chance to test the PAL dumps from the archive already present on the database.I found that all of them were correct and working in a GAL16V8 but the last one wasn’t.So I redumped this PAL and added also the missing PCB location to the filenames.
Here is the dump of the only PAL from an original Konami Lethal Enforcers (ver UAE) PCB.Dump is tested working in a GAL16V8 replacement device.Probably this PAL marked ‘054884’ is present also on other Konami PCB like happens for other ones so, please, contact us if you should notice it.
I got from a German customer this nice Fujitsu FM-TOWNS Marty console.
For the uninitiated FM-TOWNS Marty a Japanese console whose hardware is derived from its “big brother” FM-TOWNS computer.It has some of the coolest perfect arcade ports ever published like Splatterhouse, Bubble Bobble, The New Zealand Story, Tatsujin Oh and others.
As every Japanese device it has to be powered by 100V/110V so European people must use a step-down converter capable to reduce our 220V/240V to proper voltage .
This is what the owner of this console forgot to do by mistake..:)
So, after some seconds the “magic smoke” came out from the console.
Obviously the console did not power at all so i opened it and I immediately noticed some blown components.In particular the main 2A fuse was blown and a 100uF 200V capacitor was literally exploded on its top.The blown fuse was a good sign since it means he made his duty blocking the excessive current flowing in the circuit but the big 100uf 200V exploded capacitor meant that this overcurrent reached also other components before the main fuse blown up.So, I decided to further investigate.Usually the first component after main fuse and filter capacitor is the bridge rectifier (which, indeed, rectifies the sinusoidal current in continuous one).In my case there was a 600V 1A bridge rectifier marked ‘S1WB S60’, here the datasheet:

Infact, as I suspected, I tested it with a multimeter and it was shorted.
So, I desoldered these three bad components:
and replaced them with equivalent ones:
Reassembled the console, powered it and got this:
Mission accomplished.
Well, after one month of pause (real life like sucked me..) finally I’ve found a little bit of spare time to do some updates.
So, here is the PAL dump from an original Martial Champion PCB.I can’t test it since the PCB is faulty but there should not been any problem.Please, note that there is also another PAL on the PCB but it’s a 24 pin device (a PAL20L10) so out of my dumping abilities.ASAP I will send the chip to my colleague Porchy in order to dump it.
I dumped the three PALs from an original Atari Skulls & Crossbones (rev 5) PCB, an obscure arcade game, never heard of it until now.The three devices were all unlocked so I dumped them with a standard programmer and then converted two of them (a PAL16R8 and a PAL16L8) to GAL16V8 format using PALTOGAL utility.The third was already a GAL16V8 device so no conversion was needed. I can confirm that the two dumps mirrored here with the permission of Aaron Giles match the mine (same equations but different labels) so we can merge them.All dumps are tested working in GAL16V8 devices.
