That's where I got my start, first with the 41cx and then with the 71, using the HP82169A HPIL-to-HPIB (IEEE4888) interface converter, the FSI164A for RS-232, and the HP82165A for parallel.

I have a 64KB front-port RAM module from CMT, but I've never seen one on eBay. I also have a 96KB from them for the card-reader port, and they also had 128KB and 160KB but I didn't have the budget for those. These all had lithium backup batteries so you could remove them (assuming they're FREEPORTed) without losing data.
