IBM 49/50 key with PCB

So I am putting some serious thought at replacing my Orbweaver with one of the IBM 49/50 key keyboards. The problem is I don't like the feel of M. I would rather keep the Orbweaver. So with this, is the 4704 banking series the only ones with the pcb style F internals? There are 4 of the layout on eB...

I just want to say, if corrosion resistance is the primary goal, I would reccomend a dry film lube as well.

I would bet that Corsair's keyboards are topped with aluminium. There are different alloys of aluminium, some harder than others. 6061, also known as T6 is a common type, often described as "aircraft grade". Just wanted to clear up a bit of misinformation here. The 6061 is the actual grade of the a...

Was there a buckling spring keyboard with a single unit number pad 0/INS key? Or is the closest the F XT with the stepped version?

By disassembling one of my Model F keyboards' inner assemblies and gently/slightly increasing the bend of the top metal plate only, I was able to improve (increase) the crispness of the keyboard significantly. I did not replace the foam. Putting everything back together required more clamping thoug...

Grats on the win. To answer your question yes just remove the barrel inserts and insert a spring/flipper. As far as modding goes idk if you will need to source springs or not. Also as other people have said soarers converter should work. Another thing you may need is replacement foam if yours is ba...

As a kind of "proof", here you can see my F AT with some remappings done with Soarer's converter: DSCN3478 Klein.jpg Looks good.

You don’t need any built-in converter for an AT keyboard in general, just a passive AT-to-PS/2 adapter (and possibly one of those PS/2-to-USB adapters if your computer doesn’t support PS/2). The numpad can definitely be a 4x5 matrix, but I’m not exactly sure how the extra keys get reported to the c...

Not that nobody over there knows IBM but seems be be more knowledge sharing on it here. My plan is to obtain an IBM AT for ANSI conversion. I am not to wo...

Sorry for the necro bump but I am attempting to use this to reverse engineer an odd ball F and I am getting output from the teensy with hid_listen but am not getting anything in scla. I am running this on a laptop with XP SP3 as my windows 8 rig lacked the requisite dll file.

Unfortunately, this variant uses the 8-channel controller chip 8273565 (the square silver chip), so Soarer's controller can't be used with this (see his post here: https://geekhack.org/index.php?topic=50437.msg1148867#msg1148867 ).

Much thanks to hwood34 for selling me this exceedingly hard to document piece. Anyway enough of the formalities. While this may LOOK like a 5291 "Bigfoot", the internals are totally different along with different legends. The best I can tell it cam from the IBM 5324 system. There seems to be very fe...
