Does anyone know if the Electric RailRoad Cruise Commander and the old TrainAmerica Studios Engineer-On-Board electronics will play nice together in a "lash-up"?
Are the speed steps the same? Will the "nudge" feature of the ERR boards help these two differing systems work together?

My sense is it's unlikely if you're using the cruise features. I have both systems, but I've never tried to do an MU with them. The acceleration curves are quite different between the systems.
I'd just try it, I could easily be wrong. 
Yet another reason Im still a huge fan of DCC, the ability to speed match locos for MU consisting

If you get a chance, can you try and MU a set for me and see how they run? I don't have any ERR equipped units yet and I want see if they'll play nice with the TAS-EOB units I have before I upgrade. If I have to, I guess I'll replace the TAS-EOB with ERR boards, but I'd rather not have to replace electronics that work just fine.
It'll probably be a while before I can get to this, but I'll bet someone here has those sitting out and ready to test. 
They don't work at all well together. EOB has lots of built-in acceleration momentum whereas Cruise Commander has none. When starting out, the CC locomotive will try to drag the EOB locomotive until EOB catches up. Once running at speed, the locos might or might not fight each other. EOB has 128 speed steps while CC has 100. When slowing down, the CC loco will slow down sooner and momentum will make the EOB loco try to drag it along.
That was my feeling Bob, that's why I never bothered to try it. 
That's the kind of specific info I was looking for Bob. Thanks everyone!
You can set both the EOB and Cruise Commander to run at 32-speed steps. Thirty-two is the default setting for the EOB whereas 100-speed steps is the default setting for the Cruise Commander but it can be run at 32 by pressing AUX1 + 0 + AUX1 + 0 + BRAKE on the CAB-1, CAB-1L or CAB-2.
I still doubt they will be compatible since the speed tables are probably different, even if both are set to 32-speed steps.
EOB and ERRCo cruise both have the ability to run open loop (cruise off) in command mode. That would be the most reliable way to MU.
The inherent conflict in trying to run two independent closed loop systems simultaneously results in large loop errors due to the drive of one system feeding into the feedback of the other. It's basically a contest to see which one will go 'hard over' first.
