Birthday came, so I was allowed to open the EBay package!
Calculator, case, and reference card all looking good. Battery pack is intact, but I have no idea of the condition of the NICADS or any way to charge them. Sad

Several designers (Nate Martin, Hans Brueggemann, Sven Gugelmann, Dave Frederickson, etc) have created several replacement parts for HP handheld.
For example: Woodstock Battery Top Part & Woodstock Battery Bottom Part
You can order a 3D print copy, from these Shapeways sellers: Nate Martin & Dave Frederickson

Edit: added designer names

I went the single piece approach using Chris Osborne's design, also available on Shapeways from MafWorld . Since the design files were available, I was able to 3-d print the holder, now I just need to figure out a decent spring arrangement to connect the cells and hold them in place. Then I'll add a pair of Eneloops, and hopefully I'm off to the races.
