I was not aware of the Computer History Museum. Thank you for bringing it to my attention. I'll contact them. Thanks.

There may be residue on either the fly plate or the circuit board. This could be sticky or just moisture.

Hi again, Mr. Harris. I know the main purpose of beamspring keycaps is imitate the Selectric family and that you were not part in the design of those, but I wonder if you could confirm if Selectric (and in consequence beamspring) keycaps use curvature continuous tops. That would explain why other ...

Hi Dick,

Was there ever a reverse dye sub legend as far as you know?

Like you dye the entire keycap except for the legend? Maybe the legend has a sticker covering it during dying

Robb, Reverse is interesting. It is new to me. We never discovered a way to sublime white characters and ...

Hi Dick,

Again big thanks. I have a bunch of questions but I'll space them out.

I have been using a 3d printer with a conductive filament to print beamspring capacitive elements. I have also tried copper tape and a conductive paint for model f capacitive elements that I printed in photo resin ...

Thanks for the reply, Dick!

Can you expand more on the ultrasonic delay line thing? I've never heard of that before.

Also you mentioned above that you wrote your own patent disclosure. When we read your patents how much of that is in your own words and how much of that was done by an ...

Thanks for the reply, Dick!

Hi, this reminds me...was the patent request for the beamspring switch rejected in the US? The switch is patented in UK patent GB1363777 (A) but we've been unable to ...

Hello, Dick! I hope you are well.

Would you happen to know more about the origins of the AT&T buckling springs that hold certain similarities to the Model M design? They have been observed to have some striking resemblances to your design but are thought to be an AT&T product. Nate, I don't ...

Hello Dick,

Would you be able to provide some insight into the key layout evolution from the F XT to the F AT and then from the F AT to the Model M? Were any noteworthy/unusual ideas floated before settling on the layouts that made it to market or was it more of a gradual evolution?

My work ...

Dick,

1. Is it true that the need for a new keyswitch design to follow the beamspring, leading to the buckling spring, was due to a new ISO standard about keyboard height?

Our design requirement was to reduce the height of the keyboard. I don't recall exactly what influence the ISO standard had ...

Thank you immensely for the time you gift to us!

1. How did the Keyboard B evolve into Keyboard F? I assume, a driving force was cost reduction and reduction of switch height. What would interest me is the nomenclature. The B, F, and M are well known models, but have there been others built? Was ...

Hi Dick. I'm glad to see you around. I have had some questions for a long time and I would appreciate if they were answered:

We know for patents and the categorization of IBM switches in general that there were a lot of candidats to be in the place which was finally ocuped by beamsprings switches ...

Howdy, Dick,

Thanks for making those buckling springs keyboards for us all, I think I speak for all of us when I say they are a lot of fun to play around with. Thanks, Keyboard F was one of the most rewarding and fulfilling projects of my 50 year career.

What kind of keyboard do you use/like ...

Hey Dick,

What is your opinion of the Model M design decision to add what I call cushions, or shock absorbers into the flipper of the Model M? It looks like a free means for a soft down stop. There may be some debris created here, but I would think that it should cause no problem.

I'd like to know where he gets his inspiration for his inventions from. What is his process?
At least during my working career, I almost always lived with at least one problem that was worth solving and that I didn’t know how to solve. These problems might come from marketing requirements ...
