A friend of mine picked up a DOA SpeakEasy for $250. Game is cosmetically in very nice shape, but it doesn't power on. He bought it from a guy that was "trying" to fix it. With the machine there were 3 MPU boards.

He dropped the machine off with everything. A few weeks ago. 2 of the three. Mapau's were severely corroded. The third didn't look to bad. I cut the NiCd battery off immediately. The board didn't boot, so I looked it over and found a couple minor pin issues. I end up replacing on of the connector pins and the board powered up. It had a set of Black Beauty chips in it.

I ordered replacement ROM's for the game and installed them today. The board shows power but no longer cool,eyes the boot cycle.

My questions are:
#1). Will this stern board work with Speak Easy?
#2). If yes, there are seven sockets for chips and the game on,y appears to,need two. Is that correct, or does it need some other chips?

The light just comes on solid red and does no blinking now.

Thoughts?

Check the jumper settings. It is likely that the chips you replaced were original and the replacement chips are newer versions. Info here - http://www.pinwiki.com/wiki/index.php?title=Bally/Stern#Stern_MPU-200_Jumper_Info

That is a stern MPU200, yes it will work in a bally speak easy, but you may need to change some things. Besides the ROM jumper settings being checked like mentioned in the previous post. You will need to remove one ram chip at U13 if installed (or both and install one NVRAM @ U8 preferebly, but get the game working first). Check that clock speed is set to 0.6MHz (Jumpers 31-32 & 33-33 OUT).

Thanks! Will make the changes tomorrow and see if that gets it alive.

Ok. I have given up on the MPU 200 board. Any recommendation on who I could ship it to to get it up and running?

I have sent him. Ultiple PM's, not response. He is local and would be an awesome connection if he responds.

Hi Pinside.

I have gotten myself in over my head. I have 86 unread pinside messages right now. Lately I have been getting a few emails a day about doing board work. With NVRAM sales going really strong, I am trying to get rerpo board operations up and going, have a day job, etc... I just can't keep up. Until things cool down, I am not taking in any new clients.

Sorry! I wish i had more time... maybe i should quit the day job.
