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.
