Thanks Gene

I should have said I have backed off from trying to get both drives working together and all my testing was just with 1 drive at a time.

So if I only have 1 drive connected then I should just need a jumper on 0 & Term!

However one of the drives only spins up when I jumper MX even when it's the only drive!  I'll check the edge connector.

I'm going to get my Tandy ctrl and drive out of storage and test that.

That should at least prove the CoCo is not the problem.
