RE: HP41 extension ports pinout
Potentially any existing module interface could be emulated by the esp8266.
Potentially:
HP-IL module to Mass storage
Card Reader
Cassette
Extended Memory as mentioned earlier.

I like the Card Reader housing as it should provide ample room for prototyping.
Try CC41!
