HP 15C LE (or new 12C) disassembly

[Alejandro Paz(Germany)]

Even if I would pay, say 500, for a premium quality 15 or 50g, there are none available, and there were none available at the time the 15LE was on the market.
The 50g costs much less than what a 15 used to cost in the 80s, and has much more power and functionality. Inflation and everything. But, from what we can read here, the 50g is also of regular quality at best .
On my desk, I can admire a 41CV made in '83..84 (2414A). The display has great contrast, all keys work, they have... that feeling. OTOH, the 48gx ('96) I have, have nice keys but they are the plastic bubble sort, still better as what is described here for recent models... but a far cry (imho) to those metal-dome keys.
