Thanks to all for giving the information on the needed power supply and batteries for the HP 110 Portable Plus (it is indeed the Plus). In particular, thank you for correcting the power output of the 82059D as being 8v AC under load. (My source for it being 6 V was from Mike Simms FAQ on the HP1xx series of personal computers -- he has it in there as 6 volts -- so someone may want to have that changed.)
