[pups] AVIV vs. DigiData tape controller

I've got an AVIV TFC-825 UNIBUS controller on my 11/44.  I'm virtually certain
it emulates a TS11.

It appears to support Pertec formatted tape drives.  It has two
cable interfaces, labeled Pertec P1 and Pertec P2.

I currently have a DigiData Pertec formatted 9-track drive plugged into a
DigiData controller on my QBUS 11/83.  Works fine.   Now I'd like to use
the drive to bootstrap the 11/44.

The DigiData drive's cables are both 49-pin ribbons.  Sure enough,
the DigiData controller's cable headers are also 49-pin (what a wonderful
world, eh?)

However, the AVIV controller's cable headers are 59-pin!

Anyone have any insight into what's going on here?  Isn't a Pertec
interface a Pertec interface?  Or is the DigiData using some kind of
proprietary (to DigiData) interface?
