HP 71b: Oregon Digital Serial Plus II Manual - Michael Fehlhammer - 11-21-2020 11:38 PM There are different variants of protective cases for the HP 71b from Oregon Digital; the Serial Plus II seemingly is the top version. In addition to a serial interface it has got 128 kB RAM and a single line LCD that typically is used to display a menu. A short description of the device can be found in edition 2-3/88 of W&W magazine "Cursor". I have got the device but unfortunately not the manual. Manuals for the simpler Serial Plus versions don't describe the programming of the LCD. Has anyone got the manual? |
