The 16 line display version is the original HP Portable (HP110), not
the PortablePlus.

They both use the same AC adapter/charger which gives 8V AC. It's the
same unit used
with the Topcat calculators (HP91, HP92, HP95C, HP97, HP97S) and most
of the HPIL
peripherals. There were various versions with different input voltages
and mains plug
connectors but it shouldn't be hard to find one.

The Portable and PortablePlus have an internal lead-acid battery.
Originally 3 Cyclon
cells (2.5Ah) in series, later a Panasonic (IIRC) block. The Cyclon
cells are not
difficult to get new, so I normally wire 3 of those up, using the
terminal plate from
the original battery pack.
