Error code 61

[Jim]

they are worth keeping, like knagl said, the 61 loop probably needs to be cleared. for next to nothing you can put a socket on the board and never have to remove the board even if the eeprom did go out. there are only some resistors, bypass caps and the chip and its components. not much could go wrong.  if the resistors aren't burnt , then you have a damaged trace. you can usually spot those pretty easy. they too can be repaired.

The 2 others I installed did not light any led's to show coins or anything.

Hey guys...What if he has a bad power harness coming from the power supply? 
You think he might have a badly oxidized ground receptor pin
in the PS harness Molex in these "other 2" motherboards?

Thanks for all the help. Machine is working great. I have an older s+ triple diamond and would like to have an external bill acceptor. Are they available and how difficult are they to install?

[knagl]

There are side-mount bill validators available that can be added to an S+.  There are plenty of them out there, it's just a matter of finding a vendor who kept some in a back room and didn't toss them.

They're not too difficult to add -- you need to drill through the cabinet to mount it, another hole for the wires, and then attach one harness to the motherboard, and two wires to the power supply distribution block in the bottom of the machine.  Then, you enable it with the use of a SET chip like an embedded validator.

If your goal is to just more easily add credits to your machine, it would be cheaper and easier to get an SP chip that supports tokenization.  With tokenization you could, for example, tell the machine that one coin = 25 credits (essentially making it a penny machine), so if you put in 4 quarters you'd get 100 credits on the meter.

[therockinelvis]

The SP chip sounds like a good way to go. So each coin in would equal 25 credits. Would hitting max bet only remove 3 credits?

yes, providing your game is a 3 coin game.

[knagl]

Correct, if it's a 3-coin game.  You can set it to give you however many credits per coin -- 25 was just an example (although if it's a quarter machine, setting it to 25 per coin is a good way to make it a "penny" machine that takes and correctly credits quarters).

(Edit: Sorry, Bunker, didn't see you had already answered that!)

Also, if you have 78 credits and press "cash out", it will spit out three coins at you and leave 3 credits on the meter.  You must play out the credits that are a fraction of a token, or win enough for the next token value (25 or more credits).

You need to have a 10mhz board (most S+ machines do, although some are running the newer 16mhz board), and then use a SP1137 chip in place of your existing SP chip.  You'll also need to get a SET086 set chip to program the tokenization settings.  Once you get those chips, we can walk you through the process.  The classifieds section is a good place to post a "WTB" (Want To Buy) message for the vendors who frequent this site -- they'll be able to get you the chips you need.

If you have a blue volume knob sticking out of the top of the MPU board in your machine (behind or next to the hopper, depending on the age of the game), you have a 10mhz board.  If you're not sure, take the board out (make sure the power is off first) and take and post a picture of it here, and we can verify it for you.

lol...that's okay...I didn't have time to put in a better answer like yours...
I was running out the door at the time I answered that one...

If you do put a BV in it, and with the right chips, you can retain the quarters giving proper credit and payouts, but have the BV give more credits. For example 1 quarter = 1 credit, but $1 bill =100 credits.
