Hmm now that I'm reminded that a large proportion of Commodore's
"stuff" was IEEE 488 or a serialized version thereof.

I kind of want to see now if an IBV11 and Commodore 1541 can be abused
into cooperating. (There'd need to be a small "box of stuff" to turn
the real 488 bus to CBM's serial thing.)

I'll second this; many thanks for sharing the official DEC RT-11
drivers and code.
