Re: Decision Data terminal keyboard (IBM 5251 clone?)

That's a nice one. I actually really like the old "vintage" Key Tronic F&F switches. It's a sharp looking board and good job with the retrobrighting!

Re: Alps restoration guide

That's two different product, wich one did you suggest ? PTFE ? Silicon ? Both ? My bad for being confusing. I've used the WD-40 Silicone spray not the PTFE versi...

Re: Hi-Tek high profile terminal keyboard with a few quirks

I have some very cool looking boards that also have Hi-Tek high profile switches - I wish there was a way to make them nicer to type on! I've tried silicone based lubes, which do...

I've been using 3% peroxide with good results for a while now. I use a glass pan under two 90W halogen lamps, typically for 6 - 8 hours.

Re: Do you type properly?

Of course I type properly. I just don't keep my fingers on the home row, use two to four fingers (just depends) and do peek at the keyboard. The letters seem to come out in the right order for the most part so I'm happy.

Hi, OldIsNew, may i ask if the 3rd generation leaf spring used in this keyboard are clicky? Or linear? I intend to believe its linear according to wiki info but better ask that for 100% sure.

Re: Coming Soon - Through Hole Universal Model F and Beamspring Controller

A relay costs less than 1 eur and a DC DC Boost converter also costs about the same. So for just 2 euros in additional components you can drive a solenoid. If you buy a 5v solenoid, then you dont even need a boost converter - all you need is a 1 euro relay. Yes it's pretty straight forward with a 5...

Re: IBM Model F AT - shift/enter key issues

Are the stabilizers for the keys seated properly? If the keys are working with single unit keycaps, but not the larger stabilized keycaps, that could be the source of the problem.

Re: Coming Soon - Through Hole Universal Model F and Beamspring Controller

I really like this idea. While commonsense is very cool, I have found it tricky to get rebuilt F&F boards working well with it. The xwhatsit has always worked smoothly for me and a through the hole version would be great!
