I don't have any kind of docs for a tape-only system though; only ones
for disk systems - which happen to describe tape procedures too. Maybe
you have some different ones. It was more that I'm surprised they didn't
say in the docs that it was an RML part, or avaialble from RML or
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.

If you can stand a PDF I think this is the one :-)

http://vt100.net/rm/docs/RML_380Z_cassette_operating_system.pdf

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)
