Advice on a 122-key Model M
« on: Wed, 06 March 2019, 19:50:43 »
Hi.

Every now and then I get the Model M bug and buy whatever keyboards I get my hands on.

I suffered at least 2 episodes of it and I'm now getting through the third.

So I paid a visit to the place I store my Model Ms and was surprised by this:




It has an attached cable:



With this connector:





Which, according to this DT page is an "RJ11" connector.

According to the label in the rear, it is a 1390587 P/N built in UK in February 1989. The keyboard is in pristine condition. I haven't opened it yet, but it doesn't sound like it has any broken rivets.

Assuming that this is a terminal keyboard, I seem to understand that a mere RJ11-PS/2 adaptor (if such thing actually exists) won't make it work. This reddit page says the cable is AT protocol and that I should purchase one of those cables with an integrated Soarer's converter from the eBay user orihalcon, but links to a cable whose plugs have no resemblance to this.

I think that what I need is this cable, but the listing talks only about the Model F, so I would like any of the knowledgeable individuals in here to confirm.

TIA.

Caps are very rare, I also have 2 m122s but the caps are quite different.

It's a spanish layout keyboard. The blank keys do actually have keycaps on, so I think they are meant to be blank.

That is not an RJ-11, it is a 240-degree DIN plug.

Orihalcon makes one that works great.

PS - your orihalcon picture shows an "AT" socket which is a 180-degree DIN

Mr. Obama came to an agreement that did not involve America’s most precious treasure, the lives and limbs of our soldiers.  The 1.7 billion dollars of frozen Iranian assets released by Obama pales in comparison to the 300 billion being floated as a rebuilding fund.
So far, speculation that Iran will be free in the future to continue its nuclear program is the opposite of Trump’s stated goal for the war and in direct opposition to what Mr. Obama negotiated."

I see. Thanks. It seems that the GH wiki entry is mistaken about this 1390587. It should read "Coiled & attached cable ending in a 90°-angled 240° 5-pin DIN connector" instead of "RJ11, coiled & attached cable".

Thanks again. I guess that what I need is this orihalcon cable.

That's the one. It will also work with the 122-key Model F when you decide to upgrade to the Emperor.

Contact Orihalcon directly through the forum and save a couple of bucks off the ebay price.
