  You were lucky! Most people got stuck with a chicklet keyboard on those.
You still see ads occasionally for people looking for standard keyboards.
The batteries are to hold the CMOS settings. Yes, they should be N cells.
They use the same arrangement in the HP 150s. The HP-IB port is used to
connect to disk drive(s), printers, plotters, etc. The HP_IB supports up
to 32 devices on the bus but most items only have a four pole address
switch so that limits the number of available addresses to 16 including the
computer. And often the computer reserves several addresses for it's own
devices, but I don't know if the 120 does that or not.

  I've never had (or even seen!) a 120 so I can't give any specific help on
it. But I think I have a chart showing what drives are supported on the
120. Let me know if you need a copy. HP_IB disk drives aren't hard to find
and HP ThinkJet printers with the HP-IB interface are plentiful so grab a
couple and hang them on it.
