61 code on S+

[dale]

I have a MPU Board that has a Double Dollar game on it that I swap out when I change games. When I put this in I get a 61 code, push the white test button and instead of a 61-1 it initializes and is ready for play. Why does this bypass the 61-1 codes? My other MPU boards that have a Hot Peppers and Double Diamond go directly to what the game was at when I changed them out, reel position and credits so I can continue play right where I left off. The SP chips are all 732. I would like the Double Dollar game to also pick up where I left off when I change it out. Any help is appreciated. Thanks.

It could be something that was not yet written into the older chips themselves.
I have an older SP050, and an SP605 that bypasses the 61-1 as well...
mainly because I believe there was no such thing as a 61-1 at the time
when those chips were designed.
The newer ones like SP1271 nearly always need you to hold the test switch
for a few seconds before you get to the 61-1.
Of course, the next step is to close the door and turn the reset key to "boot" the game.
My guess is that they added additional code into the later chips so the machine could force
the attendant to reset the game data?
I could be way wrong as I don't know anything about the programming of these chips.
It's only a guess...
In Rick's FAQ Files on top of every home page you will see what these codes mean....
albeit they're pretty vague and give extremely short descriptions but these are examples
of what you are actually doing  when you're pressing buttons and
turning jackpot reset keys and closing doors>>>

61 Bad CMOS RAM
Open door and press self test button for 2 to 3 seconds.  See 61_1.
61_1 Game data reset
Close door and turn jackpot reset key.

So you are thinking the SP731 chip does not have 61-1 code? This will also not hold the previous play information which is my main concern as I like to be able to start play from where I left off. I have SP731 chips in the other two games I change out. I could try one of the other chips to see if that is the problem.
What are your thoughts that the MPU board itself may have can issue?

Something's not right because according to the PSR for your chip,
there's supposed to be a code "61-1" written into it.
Like I said, I'm not exactly sure what's written into the chips themselves
so it's hard to determine exactly where these codes are originating from.
It's possible that they are part of the MPU's microprocessor chip too.

"61-1" means the game data is resetting.
The game data is written onto the SP chip.
The "previous play information" is another story - that accounting information
stuff is written into one or two separate chips.
One being the CMOS and the other being the small 24C04 chip on the motherboard.

Lore has it that, that information is re-written over onto one or both of those chips during
the 2-3 seconds "pause" after every 100 pulls.
I would try pulling your existing SP731 chip and replacing it with another SP731
just to see if you first get the "61" and then the "61-1" code after pushing the test button.
You may or may not get them because the chips should be the same.

I want to try a totally different game on a MPU such as a SP1271 and
some compatible chip, clear everything with a clear chip and then change it all out back
to the SP731 and it's compatible chip.
May I ask you, what SS chip you using with your SP731 and what board is it on...
a 10MHz or a 16MHz board?

I have a 10 M board, and SS3203 reel chip. I did a Ram Clear, BV set, got 61 but did not get a 61-1. I did get a 65-2 but opening  and closing the  door cleared that and I still did not get a 61-1. It plays fine and writes information every 100 pulls. I did stick my Hot Peppers board in and it came up with a 61-1. It seems like a chip or the board. I should  get a new SP731 from one of the vendors. Thanks.

[stayouttadabunker]

Interesting..."65-2" means there was a "game type mismatch".
The way to clear it was to push the test button...huh? 
You have weird acting machine...
but you know what,  it works!
"If it ain't broke - don't fix it!"...lol

Take a look at these>>>

Oh yeah, I did press the test button on the 65-2 code. I have a printed copy of the FAQs and followed them. The machine itself plays fine and resets with the Hot Peppers board as it is suppose to. Do you still suspect a bad SP731? Thanks

A SP-731  will give you a 61-1  after trying to clear a 61 code.  I was told that was a level of security that was not on the earlier SP chips

The SP chip says it is a 731. I will ask one of the vendors for a replacement SP731. Thanks to all that helped.

As far as the SP731 game chip,
I must respectfully agree with Jim...
please allow me to quote from the SP731 PSR sheet.
It appears that there's mention of both the "61"
and "61-1" error codes as well as others.

So you can get either a 61 to 61-1  or a 61 that bypasses and goes directly to play mode? The SP that bypasses probably does not save your previous game credits when you change out. Just as long as nothing is corrupt. Thanks.

[stayouttadabunker]

Somewhat...but one thing for sure -
your game will play and you should be okay without any problems.
Thanks for bringing up the interesting questions!

Now for my testing results off of "Young Frankenstein"...

Purposefully, I inserted an SP chip that had a PSR that mentioned the dreaded "61-1" error code.
I installed an SP731  with an incompatible chips such as Double Diamond Haywire SS4267.
"61" came up, I pushed the test switch, got a "ding" sound and "61-1" popped up.
I closed the door and turned the reset key - up came "65-1" (That was expected)
I then opened the door and pressed the test switch again and up came error code "68".
"68" means "Non-compatible Data Prom" (Fully expected result!)

Okay, I then ran a Clear chip (twice) in the SP731's Game Prom socket location.
Removed the Clear chip, then installed a SP731 & SS3203 chips similar to Dale's set-up.
I got all the expected "61"/ Test switch/"61-1"/ close door turn key/ boot into game mode results.
This set-up does NOT bypass the "61-1" at all.

More testing later but next time with chips such as SP050, SP450, SP557 and SP605.
Will post results soon!

Fantastic results!!!!
I installed a very old chip named SP050.
(I remembered the jumper for the GAME PROM" socket needed
to be moved over to the E15 & E16 position for the oldest 10MHzchips)
Turned on power, and "61" pops up, pushed the test switch and
the MPU COMPLETELY BYPASSED the "61-1" error code straight into code "65-1"!
I pushed the test switch one more time and the game initialized ready for play!

[dale]

Thank you. Glad I could provoke some thought from this intelligent crew  . Would these older chips not allow you to save previous play information after a game change? For instance, I have 100 credits on the Double Dollar game and want to change to Hot Peppers. Play HP for awhile, decide to go back to DD and have my 100 credits and continue play as if there is no interruption?

I don't think that's possible because anytime the SS or SP chips are changed -
the CMOS or 24C04 motherboard chips gets cleared out and loses previous accounting information.
Whether or not the older SP's clear everything remains to be tested and seen...
Changing both SS & SP chips sort of make the MPU acts like it lost its power -
quite similar to removing the battery on the MPU board.
The battery's sole responsibility I believe, are to retain a very tiny amount of
power to certain legs on the memory chips when is electrical power is out like in natural
power outage or when the machine is move to another area in the casino.
