My guess, based on one of the 9800 interfacing manuals, is that it's 
just a normal 8 bit binary interface module for said calculator with the 
right calbe and plug. Now I have to try and remember the number for said 
interface -- it's something like HP11202 or HP12202. 

Incidentally, I am looking for any spare (as in cheap!) interfaces for 
this series of machines. I have a couple of 9810s and a 9830 that I'd 
like to hook up to other devices. If all else fails, I'll make my own as 
ever...
