I don't have a manual but I think I *may* have an interface for it

I don't remember it having a DB-25 connector.
The 9825 interface for the 4070 was the standard 16 bit interface module
with the right links on the connector board and the right cable.
Exactly. It was an option on the regular GPIO interface. HP had lots of
options for this interface so it could be used to connect different things.
I have a list somewhere and it shows at least 15 different available options.
The
4070 interface is similar to the centronics interface,
BTW, but some
of the signals are inverted, etc.
BTW, I have the operating/service manual for that interface module, and
it misses out details of how the cables are wired and what links are
fitted for the various devices. Does anyone have that information?
No, I wish I did. I've been looking for them but haven't found it for
any of the options yet.
