HP41 display for DM41?

Post by Krauts In Space »

Any chance to see a DM41 with a 14 segments-digits display?
Right now a DM41(L) with dot matrix doesn't tempt me, but maybe with some nostalgia?

(I know, this might need a special display driver, other than the dot matrix drivers and displays from the shelves - just let me dream a little ;) )

IIUYC, then you want an outdated display for nostalgic reasons, don't you? If I'd be a company, I'd let engineering estimate the coarse costs to fulfil your wish, multiply by pi, and offer you that price.

I'd be right there with my checkbook ready! Never underestimate the power of nostalgia. Look at the selling price of vintage computers such as original Altairs on eBay!

If I buy someone a drink to congratulate them, is it a Mazel Tov cocktail?

Chris Chung had them made by some chinese display shop for his NP-41 (surely not for an exorbitant amount of money).
Having one, I can assure you, that the result is quite lovely...

Well, my proposals on some slight improvements on DM1x calculators were answered a la "That's the way folks know them and want them." Even such a trivia like pressing the f- and g-key to delete accidentaly keypress had been rejected.

Changing that behaviour would mean rewriting the HP ROM, it's not something that can happen with tweaks to the emulation layer.

Not going to happen!

Yes, I remember I was told before and forgot about that. Sorry.

Outdated? Perhaps - or not. I still see it as the most elegant, best designed displays. Well designed.

Why not? Would that require too much work or is it simply impossible from the technical standpoint?

Not at all.
This is Chris Chung's replica display (made in China, of course) used in his NP-41.
