Like with the BB2 proto, these will be of no use to anyone really. What makes them even more useless is the fact that one of the PALs is missing so we cannot even get the game up and running.
A massive shame that 1 little chip can essentially destroy this unique item but this is exactly the reason why I started the PAL dumping mission.
Brought a few of muddymusic’s PCB’s back with me from the recent Play:Expo. One of them was an original Willow PCB set.
The original fault was some lines through all the graphics but when I got it home there was nothing at all. I found with a little flexing of the B board then the game would run so I set about replacing the sockets that I know are quite unreliable in their old age. This didn’t make any difference.
I started checking the connectors that connect the B board to the A board and found 2 pins on CN2 that had no continuity through. These corresponded to A0 and A1 for the program ROM’s so that would explain why it wasn’t booting. Luckily Ive amassed a lot of CPS1 boards over the years and desoldered a 32 pin connector from the donor board and the Willow board.
This is what I got
The jailbars are back.
Luckily, I was expecting the C board to be broken before I got the game so I had modified the program code to use a B_21 C board instead.
This seems to now work fine but more testing will need to be done. This will most likely do until such time a new Willow C board can be found.
Zabanitu has dumped a CP1B9KA PAL from his Pang 3 PCB.
It looks to be slightly different from the CP1B9K one in MAME.
Thanks to Zab for this
Today I dumped and added the 2 PAL chips from Taito’s Growl.
Both PALs were unlocked and I have converted them to GAL and tested them.
Both sets are added.
Thanks to muddymusic for loaning me the PCB
Following a bizarre occurrence that happened to caius when trying to dump the IOB2 PAL from the World Warrior board that uses it, I set about looking for one myself. Help came in the form of rcantor77 from the JAMMA+ forum who very kindly brought it to Play Expo for me to dump.
All went well and caius has now tested it.
Not a commonly used chip but it is one of the few CPS1 PALs left to dump.
Thanks very much to rcantor77 for supplying the chip, caius for testing and Charles MacDonald once again for his excellent PAL dumping hardware as without it my archive of PAL dumps would not exist.
