Data General MTB Reference Sought

[Stephen Merrony]

Does anyone have (a scan of) a manual that covers programming the MV-era 
MTB tape controller?

I have a 1980 "Peripherals" manual (014-000632-01) from the 
"Programmer's Reference Series" which covers the MTA type, but it seems 
that the MTB behaves a bit differently and I am missing some information 
for my current project.

Thanks,

Steve
