HP Portable PLUS Prototype - Dave Frederickson - 07-06-2014 04:28 PM Here're some pics of my Portable PLUS prototype. The computer was received with the enhanced display, but has been returned to it's original configuration thanks to a forum member. Click images to zoom. That's the Portable PLUS side of the 82985A Monitor Interface where the battery door is located. The serial number has been penciled-in to be visible. Note the 9999 date code. Boot screen showing the Config EPROM version 1. Production units had alpha versions. The motherboard doesn't have a battery disable jumper and the plastic shield over the battery's positive terminal is hand-made. Dave |
