ABI Boardmaster 4000 fan replacement

Been using my new favorite toy a lot and I just couldnt deal with the noise the fan made so decided to sort that out.

This is the stock fan

After doing some searching of the stock fan, I came up with this info:

Noise Rating:33.5dB

The fan is 60x60x25mm, 12VDC and finding a silent replacement was a doddle.
I ended up ordering this little fella from QuietPC.com

The original is “hardwired” into a power connector so I had to do a little bit of splicing to wire it in but other than that there was no problems. The new one even came with rubber mounts so I didn’t have to fight on getting the lower bolts back in.

This is the end result and it runs at 15dB so nice and quiet.

CPS1 Cadillacs & Dinosaurs PAL dumps

So I spent the remainder of my free time tonight dumping 5 PALs from my CPS1 Dash C&D board.
All tested working.

CD63B
D7L1
D8L1
D9K2
D10F1

I also dumped a PAL from my Final Fight board. Its marked up as LW10 (or LWIO?) but MAWS did not reference it at all for Final Fight, instead it shows a IOB1 in its place so im guessing these 2 are interchangeable. The list over at arcadecollecting.com does state its LW10 though.

Think ive covered most of the CPS2 PALs that I have in my collection. Time to start on the CPS1 ones.
Ive included a couple of ones that are already in the MAME sets just because I spent a bit of time on them before I realised MAME did have them present. The other 2 are classed as “No Dump” according to MAWS.

C632
IOB1
STF29 – From Street Fighter 2 World Warrior (location 1A on B board)
S9263B – From Street Fighter 2 Champion Edition (location 1A on B board)

More CPS2 PAL dumps

I have dumped and tested the following:
BGSB3B PAL – I found this on my Dungeons and Dragons: Tower of Doom board
C2VA3 PAL – This is in the black all-in-one boards. Not sure if its the same for all games, this is from Marvel VS Capcom

I had an issue with the BGSB3B one, it didn’t work initially and just gave a black screen. Doing some logic analysing of the original PAL showed that pin 12 was permenantly LOW and on mine it was set HIGH.
I don’t know or understand a great deal about programming PLDs but I think that pin 12 is set high by the line “!B0 = ‘b’0;”
I think this means set to binary OFF and maybe if its active low then these things are swapped. This is all a huge assumption and am probably way off but by changing the above line to “!B0 = ‘b’1;” all became good and well so I’m claiming it as a victory.
