Title: IBM Model M DIN5 to USB?
Post by: squirrelschaser on Wed, 02 May 2018, 13:58:05
Some questions

So I bought a Model M with this connector:https://imgur.com/a/49wVeUv (https://imgur.com/a/49wVeUv)

This is DIN5 correct?

I know I can get a DIN5 to PS/2 and then an active PS/2 adapter to USB.
But is there anything out there that would convert DIN5 to USB directly?
I couldn't find anything online.

does your model m have a detachable sdl cable? if so you could prob just replace the whole cable with this: https://www.ebay.com/itm/273156390075

I just bought it so I don't have it in hand, assuming that it's detachable (looks like it), that is an SDL input connected to the keyboard, correct?

Alright, thanks!
Bit pricey, but I'll probably do that then.

this is slightly cheaper if you don't care about reprogramming keys

Actually, what's the difference between the link you posted and this? https://ebay.to/2JNUaNz

It's sold by the same guy, and it seems like it does the same thing, but for cheaper.

Thanks,

think its the same as the white one I posted earlier. only difference is the more expensive one lets you reprogram the keys.

I never knew that Orihalcon made SDL-USB cables with and without chips. Definitely worth the extra $10 if you plan to re-program any of the keys.

The super-cheap way out is to go with a DIN-5-to-Mini-DIN-6 (PS/2) and then a PS/2 to USB as the AT and PS/2 signalling are electrically identical and these items are very common.
