Is there any source of info as to what the formatted drive has to look 
like? I would be willing to write a program that does this, as long as I 
can find out what the required format is. 

I have a sick RD53 and would like to get it going again. DEC won't let me 
use their diagnostic tape, and no one I can find has a Microvax 2000.
