S2000 ERROR CODE

[millionaire2k]

It's not a setting, assuming it accepts old 100s. 

The "new' 50 came out over 25 years ago.
The "new" 100, 10 years ago.

The firmware in your validator is somewhere between those dates.

You would need a firmware update for the bill validator to accept the new 100s.  I'm also not sure how to update it (nor do I know if we can) as it has never been an issue I've come across.

This slot was working fine for a couple days, now I have a couple new error codes...

EEPROM Error
and
EEPROM DEVICE ERROR -0x4

Before I got it working, I believe someone mentioned that I might need a new SB001000 stepper base chip??? Are these known to work sometimes and not other times? If this is the problem do I just replace the chip, or will it need keyed again also?

Thanks!!!

Some more strange things...

I have a 1952-0 board, I assume this is what you call a 520 board?

When I use my IVC00224 clear chip in the machine, the top light is solid and the second light is flashing. What does that mean when they both aren't solid?

Thanks, Mark

No such thing.
You either have a 502 or a 504 MPU.
Did you NOT read Reply #18?
They suggested that you post some pictures.

Here's my board...

[lookes]

SS Chip is installed wrong.

[Pinaddicted]

I've changed that SS chip to a SS6992 since that pic was taken, the new one is installed correctly, everything else is the same.

The SB chip isn't fully seated.

You may need to change the 8-pin chip (16k, Serial, 24C16) on the backplane board, as it would be positioned in an upright cabinet.
IGT calls the backplane a "motherboard".
That circuit board IS etched with the word "MOTHERBOARD" in white lettering, it's same thing really.
Anyways, when that memory chip has problems, that error shows up on the VFD display.
Slide out the MPU, take a clear photo of the backplane board the MPU slides onto, and I can show you the location of the chip that needs to be replaced.

I'll take a look  for some backplane drawings and see if I can post it for ya.

***UPDATE***

Okay...I found an old picture I took of a 960 backplane board.
You can clearly see I've pointed out the EEPROM chip in the socket at location [U2] with a green circle.
It's orientation in the socket is upwards, as noted by the indentation on the device body.

Thanks for the response, I located that chip on my backplane board. Looks like the board will have to be removed to be able to get to that chip.

I have an unused 8 pin chip along with 3 others mentioned earlier that came with the slot from the previous owner, maybe that's the correct one. I'll have to check the numbers on it.

Update.... looks like the unused chip I have is a 24C04N

[Stayouttadabunker]

The backplane board doesn't need to be removed to take that small 8-pin chip out of the socket.
Slide out the MPU, use a simple, small bent screwdriver to pry it out patly at both ends, little by little, then reach in and pull out the chip with your fingertips. 
Take your time.
This is a hobby...not a job. 

[Pinaddicted]

OK, my replacement 24C16 and SB001000 chips should arrive in the mail today. Is there anything else I need to do before/after I install these two chips?

Thanks

[Stayouttadabunker]

Take your time...make sure all the chip pins are their sockets in the correct direction.

Be careful, they can be orientated the other way too depending on the board PN/Rev.  Look at the artwork on the board and install it accordingly.

[Pinaddicted]

Thanks for the heads up, I installed the 24C16 correctly. (a little tight but I got it in) Working on the clear/key process now, I'll post the results when I'm finished.

[Stayouttadabunker]

Geat photo Tilt! 
I learned something new today on those sockets. 

[Pinaddicted]

Ok, I had it going and then screwed something up adjusting the game volume...  did a total reset/key again and now the bill validator does not work. Guessing I didn't set it to coinless in the settings?

Questions...

If I redo the key process without doing a clear, does it save all the previous settings and all I need to do is enable the coinless setting? ... or do I need to set everything again?

Thanks, Mark

[Tilt]

That's correct.  If you don't clear it the only thing that will get changed is whatever settings you change using the keychip.  Coinless mode disables the hopper and the coin comparitor.  Try doing a netplex autoconfig, that may be all it needs.

[Pinaddicted]

How do I do a netplex autoconfig, doesn't it do that during boot up or am I thinking of something else?

Are Clear chip IVC00224 and Key00045 the correct ones to use? The previous owner also gave me these three chips.... IGT S+ Ram Clear, IGT S+ BV ON/OFF, and IGT S+ SP 731

Yes they are 224 and 45 are backwards compatible with all previous clear and key chip.
