whatever.
The Disk Information File does mention a "Firmware reference manual" as
having more info on the COS tape routines and a description of the
interface - maybe that one has more details in it about the dual tape
controller. It's not a document I've seen.

Hmm... the couple of references I've seen to
it in RML documentation
suggest that it was a 3rd party thing, rather than an RML part. They
I didn;'t get that impression at all.... Incidentally, do you have the COS (monitor ROM) source
listings? They
were available from RML, but I didn't get them with my machine, alas.
If you can stand a PDF I think this is the one :-)

489KB, so not too huge either :)
I've brought a bunch of RML floppies home for the week from the museum,
so I'll see what's on those and at least make a few backup copies. Might
well be something interesting (I don't believe we've got any RML stuff
on tape though)
