[Coco] So, how do I make Drivewire go?

[Christopher Smith]

That's the file I'm using, though I can't _guarantee_ that my CoCo is unmodded.  I'm not the first owner, and somebody did throw a CoCo 3 keyboard onto it, so there's a chance they changed some other stuff around as well.  Will using the HDBDW3CC1 ROM file if they put a newer op-amp in?  I could always grab the CoCo 2 ROM, set the servers to CoCo 2 mode, and see what happens.  Worst case I suspect is precisely the same problem I have now.
