|HP Portable Plus|

Not quite, but almost, an HP calculator:
I have two HP Portable Plus computers. I've had them since about 1987 or so. One has 512Kb of RAM, the other 1Mb (not a standard configuration; it was customized by a friend of mine using parts from two PPs). Neither has any built-in ROM applications (which is why it was possible to put 1Mb of RAM in the one).
The batteries in both are dead. The 512Kb one works when plugged in, but the 1Mb one does not (I suspect that one of the cells in that one is shorted, and the external adapter can't overcome that). It did work the previous time I tried it, about 5 years ago.
I'm debating what to do with these. One possibility is to list them on the For Sale pages here at the Museum. Maybe I could trade them for one or more calculator(s).
Another possibility is the unmentionable auction site, although I don't see many of these here. Does anyone have any idea what these might be worth?
