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. -tony
