Title: WMS Ram Clear issue Post by: cp on June 01, 2010, 05:38:15 PM 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 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...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. Title: Re: WMS Ram Clear issue Post by: Pokernut on June 01, 2010, 09:03:05 PM CD
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 Pokernut Title: Re: WMS Ram Clear issue Post by: cp on June 01, 2010, 09:44:31 PM Thanks for the reply... The WMS CPU 1.5 board does have the jumpers for 8 meg sound and game eproms. I have the WMS cpu boards with the piggy back and extender board... no JP3 jumper... I'll post pictures of the CPU. The game I'm pulling out is Money To Burn which has 8 meg sound and game eproms. It is working. The game i'm trying to install is Life of Luxury / Best Things in Life.
Title: Re: WMS Ram Clear issue Post by: cp on June 01, 2010, 09:46:44 PM WMS Video with Eprom Extender for position XU2,3. Also has the piggy back board for the video plug-in.
Title: Re: WMS Ram Clear issue Post by: Pokernut on June 01, 2010, 10:12:27 PM My files for the Life Of Luxury are all 4 meggers. Check your chips, you may not need that extender board

( it does have 8Meg Snd) I've actually done this game change before several months ago...same old style CPU with piggy backs etc. Just a note here... this old style ( I'm calling it old style ) CPU is actually a ( 3 reel) slot machine cpu. Williams, came up with the add on boards when they just started producing the video slots...I'm assuming they had thousands of the slot cpu's and rather than scrap them...they developed the piggy back / add on boards...they are marked WMS / 1998. When the video took off... they redesigned a dedicated 1.5+ CPU ....(this is just a guess-timation on what was going on w/ WMS and the slot to video shift. Especially when they saw the demand for video take off. )
Still need some insight why the "new" game is not loading properly. As I can't find my WMS manual .... anyone know of the 2 bong error / issue when clearing ram ? should be only one bong... Thanks again. Title: Re: WMS Ram Clear issue Post by: tacman on June 01, 2010, 11:23:26 PM 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.

Title: Re: WMS Ram Clear issue Post by: cp on June 02, 2010, 11:53:32 AM Thanks. Jim. There are 4 surface mount eproms... mounted at the "top" (underside) of the video piggy back. I have re-checked all 6 eproms. all 8 meg. The checksums all are verified... and re-verified. The gameboards came with the machines and were working...and working with 8 meg games... I'm just having the problem of installing the Lfe Of Lux 2. ! I've done it before several months back...
Note: this board does not have the 4 meg / 8 meg jumper....like the 1.5+ boards do. Thanks to all who have tried to help. I'll put an advert in the classified for 1.5+ boards. |
