The printer displays 17 columns of text.
|Special features||Built-in printer, continuous memory.
Conversion values printed on the back of the unit for: Length, Area, Volume, Mass, Energy, Force, Pressure and Temperature.
|Original Pricing, Production||1.9.1977 ($345) - 1.6.1979 ($225)
|Batteries||4x AA battery pack or external DC 5V power with
HP-71-type connector (HP 82059A).
Important: The HP-71 power supply can be used but will only work with an installed NiCd battery pack.
A HP-71 type power supply connector can be fed from an off-the-shelf 8V DC power supply to run the unit without the need of having a NiCd battery pack installed.
Warning: The external power supply cannot provide enough current to successfully operate the printer! A fully charged battery pack must be installed if the printer is needed.
An alternative solution would be to drill a hole in the battery compartment lid and route a cable that directly connects to a regulated DC 6V supply.
The same applies to the HP-97.
