WP34S donor case from HP20B?

[Andrew Davie]

About to embark on a WP34S journey. I want the HP30B keys, as they're cited as being superior. But I like the HP20B colour scheme... must have black! The machines look pretty similar from what I can see of the photos online. I was wondering; would it be possible to simply transplant, taking the HP20B case and inserting the HP30B internals? Obviously the overlay is the same for both; but do the internals match transplant-wise?
Thanks

I have converted 20b's and 30b's to WP-34s and I guess the problem with your task is the fact that the keyboard is heat-staked to the top case and thus not easily transplanted. I contemplated that operation but have finally not tried it myself for this reason.

I am not quite sure, but I think the 20b might have fewer heat stakes.

[Tim Wessman]

No, they are very different internally. The keyboard structure is a different thickness and the heat stakes are in different spots. I don't think anyone has been successful in changing them.

It might be better to airbrush the 30b case.

Sounds like doing it like an eagle - circling and swooping
