I assume all other functions must be from the type :7 with the HP71B

I don't follow you, any controller (41, 71, 75, etc) can access any peripheral on the loop.

The 41 is the oldest controller and the one who has the most limitations.
The HP-IL module (82160A) firmware can only access 128KB tapes but if you plug-in the Extended IL ROM from Skiwd then you can access tape/disk of up to 1MB.

On some controllers you select the peripheral then do the action and on some others the peripheral selection is part of the action.

Code:

41 -> 6  SELECT  DIR
71 -> CAT :6  _or_  CAT :TAPE(3)  _or_ one of the six type specifiers
