IGT S and S-plus Reel Games / Re: IGT Double diamond S Plus, RESTORATION

The other thought on a 41/42/43 error is that the error might be pre-existing.
There is a sequence to clear the error. I am not by my documentation but it should be in the flip cards.
Finally in the top corner of the MPU there are 5 resistors.
Each one represents a reel. Typically you see 3 that are well burned and 2 that are pristine.
The S+ can be a 5 reel machine, you change out the reel shelf and harness and obviously glass and chips..
I have never seen one in NorthAmerica and I have never come across a set of chips but apparently the 5 reel versions were quite common in Australia.
If one of the resistors is flaking and falling apart you can replace it from one of the two pristine ones.
Here is the MPU. Is it those in the corrner?
