I was sincerely hoping no one would notice . I wasn't happy with the mood of it and it was getting late for copy editing, so I took it back, I'm sorry for the inconvenience.

The first part was OK:

Quote:Actually the 84 has an ASIC for both and the 89 has its memory in another ASIC. We're talking about Texas Instruments, they should know how to design these things.

(Eh? I'm quoting myself, how self-absorbed is that?)

At the second part I vented my obfuscated frustration about companies that don't design their ICs any more, maybe that's not fair and solely Kinpo is to blame.

I was thinking about the sudden calculator death syndrome (I own one of those hopeless sleeping beauties). After a bit of research I figured it was likely caused by writing the boot code in flash as everything else (I might be wrong, so if anybody really knows please enlighten me). You can be bored with Texas Inst., but at least they can avoid this as their ASICs should take care of storing these things.

And don't get me started with the really obnoxious things TI has done! For instance the absurd price of their calculators (although I doubt they are as cheap to manufacture as everybody assumes) comes from the even worse brain-damaging lock-in they have in education . The absurd limitations and encryptions they are keen to enforce, and above all their decision to kill and bury Derive, for which I will never forgive them.

But their hardware is fine and their programmers too.
