BRAUN ET90 "Protocol"

[walter b]

Finally succeeded hunting down this Braun pocket calculator (model 4769) of the early Nineties, featuring Dieter Rams' design. Luckily, I got it for reasonable money. Although it's just a 4-banger, it's not only a real pleasure for the eyes but also showing an interesting concept of storing the last n calculations for repeating and editing.

It came, however, without an instruction sheet, and I can't find any in the internet. I know it exists, hence the question - does anybody here have access to a scan? Would be interesting to learn about the full features and limits of that cute little calculator. TIA for any relevant information.

FYI, that 'problem' is none in this case: BRAUN made its profits by selling its products. Their instruction sheets were often just single sheets, folded many times, and were - IIRC - available through them at no charge at all for that reason. BRAUN changed its owner a few years ago (a different story) - the brand still makes its profits by selling its products. I checked their website and said sheet is just not available there anymore.

Is this one?
It looks exquisite indeed, and apparently sold at very high prices in the TAS.
Nice 4-line display... I wish the WP-34S could use this type of visor instead of the HP-20/30B series.
