Added the PAL dump from this rare beast. It is marked KNM10B.
Thanks go to DrGlitch from the J+ forum for sending me this board.
I loaned a couple of cartridges from muddymusic recently.
The F3 carts have a few different PAL chips in them and I have dumped and tested all present in the carts I have. All the chips were unlocked.
I already had a couple of F3 PAL dumps from Twin Cobra 2 thanks to Kevin Eshbach. I have also changed his PAL dumps from game specific to general “Taito F3 cartridge”.
MM also sent me a load of Juno First boards to look at. The original boards use a custom 6809 CPU that uses encrypted opcodes. The bootleg boards use a regular 6809 CPU but have 2 PAL chips to implement the encryption.
There is also a PAL10L8 chip present on the original board (marking are scratched off but is present on schematics), I havent tested yet but I think this will be compatible with the one from the bootleg.
None of the Juno First PALs are tested as the board sets all have issues.
Thanks to muddymusic for lending me his stuff.
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.
I just dumped the two PALs from an original Taito Nastar (World) PCB.Both devices (AMPAL16L8B) were unlocked so I read them with a standard EPROM programmer, disassembled into their equations using JEDUTIL MAME utility and then recompiled into GAL16V8 format under WinCUPL.Besides, I can confirm that my dumps match the ones present in MAME.Anyway I have no way to test them since the PCB is faulty so we would appreciate if someone with a good board could test them and report feedback, thanks.
After repairing it (see log here) I dumped the two PALs from an original Seibu Raiden II (set 4, Italy revision) PCB.One dump is tested and working on a GAL16V8 replacement.The other one was good apparently but when I tried it on the PCB I got sprite issues.The original device is a PEEL18CV8 and it seems that it has been programmed as registered (PIN1 is tied to a 16MHz clock signal) so we can’t do much about for now.So, this is a partial set.
