Has anyone got a copy of a Leon test rom for Wms sys3 sound board?

Hi again fellow members.
I have tried to download a copy of the Leon test rom for Wms sys3 sound board but all i get is

Not Found

The requested URL /sys37/s37stest.716 was not found on this server.
Apache/2.0.52 (CentOS) Server at pinrepair.com Port 80

this is the link http://pinrepair.com/sys37/s37stest.716

I am in the process of repairing a sound board for a WMS disco fever.
I am testing this board out of the machine on a test bench with a computer power supply (+12, -12, and GND)
According to the pinrepair website the test button may not do anything so i have tried activating sounds by pulling the input pins low one at a time (i.e. 10, 100, 1000 and so on) low and still no sounds.
amp section is working fine in machine and on testbench, I also have 5 volts from the 7805 regulator.
I have followed the guide up to checking the clock signals with a logicprobe & reset signal on the cpu.
I have Replaced sound prom with an eprom and checked that all the jumpers are correct for eprom.
I have tested the cpu in a System 11 board that uses the same type of cpu and it boots fine.
I can not go any further with out the test rom.
If I cannot get a copy i will have to buy another PIA chip and if that still does not fix the problem then i will have to buy a set of i.c's for it and remove, socket and replace one chip at a time until i sort the problem.

thanks again.

Good luck with This Beaky have a sound board for one of these aswell it's been a real bitch.   Working 100% on the bench get it inonthe game and the bitch locks up but the replacement board works fine.    Hahaha

     I'm pretty sure I have the test Rom still in the board I'll check it out when I get home tomorrow.

Hi Beaky. I was able to download it here. http://www.flipper-pinball-fan.be/

thanks mate, if the file i downloaded is not the correct one i will let you know.
When my mate bought the disco fever the board was working but it died on him. no one has touched the board since he has had the DF but some one before has replaced some of the electrolytic caps and resoldered all the +5 and Gnd pins on all the I.C's so I assume it has had problems before yet none of the I.C's have been desoldered. After looking at the large cap on the board it look like it has been replaced with a second hand one so before doing any thing else I will replace all the caps on the board.
I have suggested to my mate that he should let me refurbish the power supply as some one has replaced some of the caps with several second hand ones.
the large filter cap on the power supply has been replaced with 3 or 4 different value second hand caps to make up the correct value of one cap.  bloody amatures, I mean why bother using second hand caps when a set of new correct value caps would be under $30

Yes it's called "soundtest".
Sorry the direct link to the sound rom page didn't work out too well.
But it sounds like you found it anyway.

Ok I have used the sound test eprom and I have found the fault. 1 output on the PIA is staying low instead of alternating high and low.
I desoldered the pin and ran the test again, the pin would go high and low when disconnected from the pcb. So the fault lies with the  I.C that is connected to this pin.
it is the MC1408 Digital to anolog convertor.
I will let you guys know how i go after I buy one and install it.

p.m. sent
also there is a substitute for the mc1408 it is a DAC0808

[beaky]

I have received the DAC0808 I.C. and installed it into the sound board and all is well.
All sounds are working.  
Thanks guys for the help to locate the Test rom file.

Well done Beaky and thanks for posting your results.

I forgot to mention that the test button on this board does work when you press it.
