I have a failure on one of my engines and was wondering if anyone at traced out and produced a schematic of the motherboard. If I can't figure out the issue with this it might be the first of my EOB equipped engines to get converted to Electric RR cruise commander. One I'll miss the selectable chuff rate, how it controls the smoke unit, and I really don't want to spend the money right now.

Let me know if you want a replacement EOB board. 
Ah, stockpile of them
I'll let you know once I dig a little deeper into the issue. It's no longer puffing the smoke like it did in this video. The fan is still blowing but no longer synced to the chuffing.
John,
On another note do you have spare EOB motherboard firmware chips? I'm looking for the very first rev firmware that allows for this very control of the smoke unit for another engine I have.
Nope, no firmware chips. I've never seen them available separately.
Gary, I have a few of these boards also. How do you tell firmware versions and which ones give smoke unit control?

Sadly you can't, other than wiring her up and seeing what features it has. Different versions have you set up the pre/post pulse differently also.
Unless, you have the original instructions that came with the EOB. Might want to check there see if it mentions it in the set up section of the manual.
My understanding is that if the EOB was a separate sale it can have those features, but if it came from a Manufacture engine like Atlas or Weaver those features were not allowed. G
If I had the correct programmer for the PIC processor used, I'd try reading it and see if it's code protected. If not, you could program up the chip for the features if you had one of the more limited versions.

After MTH clamped down on TAS and others, You could request the older version firmware from TAS but you are right Atlas and the others couldn't use those features anymore.

That would be great John, I could send you the chip I have and you could program a few for me, at a small fee I'm sure.
That was a big "if". I checked, and my little development board won't directly program the chip in the EOB board. Also, since I couldn't check it, I don't know if they code locked the chip. If so, you can't read the code to program the chips.
Of course, getting those features to work on the EOB board would reduce the size of the potential market for my upcoming Super-Chuffer. 
Well get that supper chuffer working, and I'll just convert to Electric RR cruise commander instead.
Oh, it's working just fine. I'm just waiting on boards that are out for assembly. You can look for an announcement about sales in the near future.
