I do have a file but absolutely no idea if it's any good. Any way (other than burning and trying) to verify?

If you want to send me the file i'll be able to compare it to the one i got off the net ,  if it reads the same then chances are it's probably no good.
If it does read differently then it may be a good file and worth burning to try out.
pinrepairs@exemail.com.au

I'd say that whoever uploaded the sound files to the net for system 1 and early system 80 somehow did it wrong.
Out of the 4 original sound roms that i have been able to compare against , all 4 files from the net have been bad  , so going on those figures i'm just assuming that they are probably all bad.
I have not had a problem with any of the Cpu files for these games so far , it just seems to be the sound files.

The file Nick sent looks good , so send me a message with your address Wally , and i'll give you my details and can post it to you tomorrow.

Thanks for the good tip Firepower with the Pinmame roms ^^^
Seems the Pinmame roms are the same as the actual machine , well at least the sound roms are.
I downloaded the sound roms for Hulk , Torch ,Spiderman and James Bond , verified them against the original proms i have , and they are indeed identical. #*#

Turns out that the sound Prom files that i had were corrupt and they are now in the trash!

Thanks again Nick for sending the file *%*

Thanks guy's I'm almost sorted
Put my new ROM in today and it plays all the right sounds. It doesn't lock up and it sounds heaps better. ^^^
Only trouble is one of the sounds once triggered seems to play continuously.
I guess I'll have to look at all the sound lines/chips replacing them till i find the problem.
I'm sure the new ROM is not to blame for this
Isn't it always the way fix one problem and that just leads you to the next?

Again thanks for everyone's help on this ^^^ ^^^ ^^^ ^^^ ^^^ ^^^

No Ni Wumph all original!
Hope it's not the RIOT chip?
As Skybeaux suggested I'll try the 7404's first and go from there.

Just did a switch test
Switch 67 (Outhole) and 71 (10 Points) apparently are not closed.
Could this cause it? I guess I'll find out!
I'll let you all know.

Still no luck
Switches fixed 7404's changed on the sound board and Z13 changed on the driver board and also Z31 changed on the control board.
It appears that the problem is definitely on the sound card somewhere.


Any ideas where to look guys?

Have you tested the soundboard on its' own, out of the machine?  Connect power and speaker and stimulate the inputs to get sounds.  Is the always on sound present in this test?  if not then the card looks ok and I'd be looking for a closed switch on the pf that is generating the sound.

Well guys i have to eat some crow it appears that the crapy sound that i thought was a fault is actually the right sound for this machine.
Having never heard the sound work on the machine before i thought that i should see if there was any video of it on the web and there it was that same repetitive sound that i thought was a fault.
So thanks again to everyone who helped sort this out.
If you guys want to listen to the machine here is the site.

Lol!! Well you learned a lot about your game on the way, so was worth it I'm sure.
