HP Xpander

[David Whittaker]

Massimo & Dave, many thanks for the pictures. I have got the battery cover off now and discovered the problem was some double sided tape.

If someone knows how to add these pictures to to the Xpander page of MoHPC that would be great. Particularly with a close up of both sides of the battery cover and front cover. I do not think that I am the only collector that handles his calculators with cotton museum gloves (those things have no grip) and after confirming the working state just wants to remove the batteries for (the calculator's) long term storage and preservation.

That said, having operated it a couple of times I think I can see why hp might have cancelled the project. The Xpander seems too much like a learning PDA and not enough like a calculator. Sadly the big three calculator companies (hp, TI & Casio) have all neglected the engineering market to focus on the much larger education market. I think with a more calculator like opening page on the software, the addition of Bluetooth and the ability to use the stylus and touchscreen as a pointing device on the coupled computer, the Xpander still has a potential market out there alongside the current hp-Prime.
