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.

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

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.
