IBM 3471 (dome unsaver)
« on: Tue, 13 September 2016, 18:13:03 »


(forgive the potato pics)

The touch is quite firm, and I suspect even heavier than the Model M, but the tactility is quite noticeable and prominent.  I can't test when it actuates, since I don't have the soarer's converter from orihalcon yet.

As for "Quite" Touch, it is indeed quite quiet, at least for contemporary standards.

A bit odd that they decided to use alternating pebble/pearl for F row, considering F122s and BS Unsavers had them just in pebble. All in all, an extremely nice looking keyboard. It's time to make a custom capacitive PCB :)

I bought it specifically for being quiet and having touch. :D

I have considered doing this several times... but if I ever do it I'm going to make a custom capacitive PCB it'll be for a Model M SSK. Full NKRO and what not for a TKL Buckling Springs keyboard that doesn't cost an arm and a leg.

@Wingpad did you check lot_lizard's MF project on Deskthority? If not, you might be for a surprise ;)

Edit: The best thing is, the project is "modular", so if finances are pressing, you could just get the PCB and F switches. But I don't think metal plates and barrels will be that expensive to just add them too.

Wow, that's quite cool. I hadn't seen it before but now I'll definitely be keeping an eye on it. If you haven't noticed already, I'm not the most active DT user, haha.

I've received my Soarer's converter from orihalcon today, and I can confirm that this keyboard words with the RJ-45 version of the converter that orihalcon makes.

The key feel is, as expected, kind of stiff, but nothing that I couldn't handle, and it's indeed very quiet.  I'd be interested in a comparison with Topre, if only someone would do a tour in Canada!
