Yes, the ribbon cable.
The way Newtek handled this is when you bought a flyer, it included a replacement part for the Toaster to swap out that replaced the BNC connector bus on the card. This had an integrated ribbon cable that linked them. It was never a separate cable-only thing.
I only have one Toaster with this connector/ribbon on it. The other two Toaster 4000's don't have it.
I believe one Toaster is not working- it gets "Toaster not Responding" error when you try. I seem to recall this can be from it being out of adjustment/sync also, though, so I just need to test all this stuff and relist in a different thread. I will honor the order of requests, though.
