Code 51 Ram Error

[Frank A]

I have posted this a while back when the new format was launched, but haven't found a fix yet. I am getting a code 51 Ram Error on a five line Haywire Deluxe. I can clear it by pushing the white button once, turning the jackpot reset once and closing the door. When I turn it off and repower, it comes back every time and I have to do the same clear procedure. How do I make it go away and stay away ? Any thoughts would be appreciated. I would also like to re-program the Cash/Credit mode and set the bell to ring on each payout. I have attached a photo of the game and a photo of the label showing model etc. I was able to get the music to play when the reels spin by trial and error with the jackpot key which was an improvement, but I would like to be able to set options. All codes come up on the display, not in the coin window.

Thanks.

Interesting S+, Haywire.

Suggest that you replace the battery first. It may be low enough that the ram loses it data but not low enough to say bat low 12 (or some such msg)
Then replace the CMOS RAM chip. If I remember the CMOS RAM has 2 power inputs one for the 5v supply and one for the battery.

If that does not fix the problem. Then there is a issue between the battery and CMOS RAM chip.
I say this since you say machine works fine once you clear the tilt/error and works fine as long as you leave the machine on, and error reappears after turning machine back on.

Also get another S+ MPU (if that is a regular S+ MPU in the machine)

Any idea where that game came from? Those top awards don't match anything I've seen for 5CM haywire

Brian I have had many of that type game with the scrolling display and different pay schedule and most all were from US Military bases overseas, they often were 10 coin bet games, most with lower top awards, I have a set of newer chips for that type game (not type 2 though) and are marked Army, although I had a load that came from the Air Force many years back

I agree with Blueridge.
There was a lot of discussion on this topic before we switched over here.
It seems that code 51 only came up with the army chips.
Please post a close up pic of your MPU game chips.
Our vendors may be able to fix you up!

[Brianzz]

I recall a discussion of the military games, aren't they all really low pay?

[blueridgeslots]

I believe so

Attached is a picture of the chips.

Frank, it looks like you do have an army version of that game, the eproms have ARMP on them, I have attached the info for a standard 5 coin Haywire, I would try and replace the SP chip with an SP1207 and see what hapens

Thank you for the reply. I will look to see if one of my other machines has that chip. If not, which of our vendors here on the forum may have  one to sell to me ? I checked the battery and the voltage is pretty much the same as the readings on the batteries on my other machines. Any thoughts on what to do to get the options menu up and how to make the changes that I want to make with Cash/Credit and making the bell ring ?

Frank, as for the options for that SP462 that you have, I relay don't know, another sp chip you could use is SP805,
I have added the PSR, "Program summery Report" for the SP805, you can use that to go through the options on the machine, you could check with Jim at Blue Ridge Slots to see if he has the SP805 chip, and see if he thinks it
might work.

Just a note , I'm not 100% sure if the newer SP chips will work with your machine.

I tried another chip from another IGT + and the scrolling display goes blank. Will the SP 805 do the same thing ? Thanks for the sheet.

Frank

[westec1]

Frank, Like I was saying you have a rare machine there, and I am not familiar with that version, so the SP805 may do the same thing.

I'm not sure what the work around for that would be, sorry I can't be of more assistance.

Wes

[Frank A]

Thank you for your help.

I still haven't figured out this error. I can clear it and the machine works until I turn it off and repower it up and then 51 appears again. Should I just live with this ?

Sounds like your battery is not holding the configuration.

It could be either a low battery or part of the circuit that it supports.

I had an old PC that used to prompt for date/time everytime it booted.... the lithium cell had died and wouldn't hold the cmos info.

[Frank A]

I am afraid to change the battery in this machine since I don't have any manuals etc for this beast. If I have any other errors that come up, I may be back to hit or miss with the jackpot key and the reset key. I still can't reset the cash/credit option or get the bell to ring on payouts on this machine. I just posted another follow up question on the thread 61 won't clear. My Red White and Blue, IGT S+stopped working..I changed the battery when a 12 code appeared, got the 61 code and pushed the test button, got 61-1 and turned the jackpot key once and closed the door. Back to 61. Any thoughts ? Is a ram clear in my future ? I have to check my notes again on how to do the ram clear. Thank you for your help.

you could test the battery voltage and if it's low, piggy back a new axial battery by soldeing it to the tab spaces away from the low battery then remove the low battery.

[Frank A]

Thank you. I will test the voltage tonight.

Frank

[Frank A]

The voltage is good. I still have the same issue. Anyone with any new ideas ? This goes back over a year.

[stayouttadabunker]

What SP chip do you have in there now? Did you ever get the SP805 or SP1207?
And did you get a chance to change the CMOS chips with a known good one?
Apparently the battery is good but the CMOS might not be any good for some reason.
Did you try a swap with a known good 10MHz board?
I have one more really good suggestion but I need to know what SP chip you have in it at the moment.

Bunker in reply #7 pic. of the board   SP462   SS4623

[stayouttadabunker]

It just seems to me kind of very odd that the first 3 numbers of both of these SP and SS chips are the same?
I wish frank would pull out that SP462 and try something else...like the suggested SP805 or SP1207
or swap the board with another 10MHz board.
Try to pin point what's causing the problem....
we don't know if it's the board or the chips...

[Frank A]

Where can I get all of the chips that are mentioned here ?

[stayouttadabunker]

Blueridge might have them I think.
