Psychic 5 repair log #2

Apr 102018

My beloved original pcb developed once again problems after the last repair log you can read here:

Psychic 5 repair log #1

This time, the overall colour palette was pinked and all text was missing

After some troubleshooting I found again a problem with a Fujitsu ttl 74ls08, same type and week/year of manufacturing of the one I changed on the old repair log!

After changing it, the game worked fine for some minutes and then it developed a new problem

Game lost sync and became bluish

Again I decided to concentrate on the only Fujitsu 74ls08 ttls which were present on the board until I found the faulty one.

Same week/year of manufacturing and same fault: dead outputs

In addition, I found another couple of Fujitsu 74ls08 which had dead outputs and I decided to change all of them with good ones.

Now the game is 100% fixed but there are 3 more Fujitsu ttl waiting to be replaced. I ran out of parts otherwise I would have changed them immediately.

Lup Lup Puzzle PAL dump added

I dumped the PAL from a Lup Lup Puzzle PCB (a new revision that will be added in next MAME release )

PLD was a secured GAL22V10 at location GAL1 which I successfully reversed into same device.

Muddymusic sent me a Chopper I PCB to look at.
There were 5 PAL’s on this board and all were soldered in so I had to desolder them to dump.
All the PAL’s were unlocked so these are native dumps in their native format.
They will need converted to GAL format to use in a GAL chip.

Night Striker and Jackie Chan PAL dumps added

Today an important addition to our PLD database thanks to ‘coolmod’, one of our finest contributors.We have from him PAL dumps of :

Night Striker

This is a quite rare board, a 3D shoot ’em up developed and published by Taito for the Taito Z System in 1989.Board uses a lot of PLDs and some of them are present multiple times at different location.We have the complete PAL dump set (from PAL20L8/PAL20R8 and PLHS18P8 devices, as natrive dumps and 256KB binary respectively) and but for now only some have been reversed and successfully tested into GAL targeting device.

Jackie Chan

A 1995 fighting arcade game with renderized characters developed and published by Kaneko.Two ispLSI 2032A (PLCC44 package) PLDs dumped.Dumps are unested so for now we consider them as “assumed working” (as well as the all the other ones we had from this PCB) since devices were unsecured but we are looking for someone to test them back on PCB.

Thanks again to ‘coolmod’ for his contribution.

Cruisin USA link PAL, Commodore C16 PLS100 & Shadow Dancer PAL added

Here is something a little more special than normal.
A quick google search for “Cruisin USA link PAL” shows that a few people have been searching for this for a while now. I personally bought a PCB a few years ago in an attempt to dump it only to find the link up version uses a different PAL chip.
Recently TheDrunkenArcade bought the correct PCB and gave the PAL to JROK to reverse.
Massive thanks to TheDrunkenArcade and JROK for doing this and also allowing us to add it.

Next up is the Commodore C16 PLA. I made a post showing the method I used to recreate this to allow it to be programmed to an original PLS100 device. After much testing I have uploaded the file.

Finally my good friend Banjo Guy Ollie sent me IC48 PAL chip from his Shadow Dancer bootleg. The device seems to be operational but the PCB it came from is not yet 100% so we cannot test it right now.
There is another PAL on this PCB that he will be sending my way when he can.
Thanks to Ollie for this
