I have a couple WMS video cpu boards that have the "piggy back" add ons to the PCBA slot cpu. The boards were pulled from working WMS 550's. I am changing the games....(using the same number of eproms... XU2,3 17, 18, 30, 31 all 8 megs) in the initial Ram Clear I get a "squeal" and 2 bongs. Clear screen / pick the denom shows (http://newlifegames.net/nlg/index.php?topic=8134.0#) up... but no "click" sound when picking denom etc... Pull out the Ram Clear chip.... put in the XU2.... Restart gives me, again, 2 bongs... I can go to configure (http://newlifegames.net/nlg/index.php?topic=8134.0#)...set that up... and will go into game.... However... I'm getting only partial sounds and the "game play" is slow and has delayed and erratic action and erratic sound. Re-checked eproms / checksum... all OK. I have also tried to put the original game eproms back in the machine and it cleared properly... I came across another WMS that had the "piggy back" boards 4 months ago...and could change out the games with no problems... I'm also not having any problem changing games with the 1.5+ CPU's.
Any ideas ? ? Thanks. cp

Check your jumper by the sound chips, position JP3. I'm thinking your old game sound chips may have been 4 megs. There are a few game titles for the 550 that do have 4 meg sound chips

According to WMS manual- 2 startup bongs= Bad XU-30 on CPU board. Remedy= Replace with good XU-30, Clear Ram and retest game. Also verify sound jumpers for correct eprom size.

Chris, look underneath the Video Adapter (where the monitor cable plugs in) there are either 2 or 4 surface mount ram chips on that board, if 2 that is your problem, if 4 then forget what I said, you can see it without removing, older games like Mon 2 Burn and Who Dunnit don't need much, but the newer games won't work, I see everybody selling any WMS board they can dig out now, but many won't work, they were Poker or early Slot games, I can take some pics and show you if you need me to.
