This site still under construction

Some of the 98x0 Calculator Interfaces
11202A 8-bit TTL interface
11203A BCD interface
11204A was used for the 9864A digitizer, and doesn't appear to be a general-purpose I/F that was available for sale
11205A Serial Interface
59405A HP-IB Interface for HP 9830
59405A Option 020 HP-IB Interface for HP 9820
59405A Option 021 HP-IB Interface for HP 9821

Some of the 98x0 Calculator Peripherals
9860A Marked Card Reader
9861A Typewriter Interface
9862A Plotter (covered in the 98x5 peripherals)
9863A Paper Tape Reader
9864A Digitizer (two pieces, an interface box and a digitizing tablet)

9866A Printer (covered in the 98x5 peripherals)
9868A I/O Expander
