Whatsup guys, i was lucky enough to come across a IBM Model M keyboard i was wanting to restore it. The problem is its not connected via a ps/2 connecter like most old keyboards and i was wondering if anyone would know what kind of adapter i would need for this.

this is the keyboard itself

That looks like an RJ-45 connector... seems like there are a few others with RJ45 connectors floating around, but it doesn't seem like there's an obvious adapter available--likely only doable with a hardware mod.

Seems like a possible solution though, check the 2nd picture where he soldered the adapter to the points that were for the RJ-45 connector.

I found this thread on the overclock forums with someone else asking the same question. Looks like you have a bit of work ahead of you.

Alternatively just acquire a cheap model m and use this terminal model for spare keys / springs for any that may be missing on the keybioard that you pick up.

Because, young padawan, the days bygone produced great gems of technology of which even today suitable reproductions are impossible to find.

The IBM Model M is a classic mechanical keyboard - it is tough as nails and much more precise and tactile than the cheap keyboards we have today. The bucking spring contacts make for a nice click and resistance which is unique and prized by many people. It is a supreme quality keyboard, easily as good as $100+ mechanical keyboards you can buy today, but it is unique just the same and has a feel and response which is not entirely replicated in newer keyboards.

I believe the phrase "They just don't make 'em like they used to" applies.

Yup i mean remember those old cars that got 15 miles to the gallon where super huge had no seat belts and air conditioning, but omg the chrome and metal and wood clearly better quality car then ones produced today with it's light weight composites and plastics. Things tend to no longer sell for a reason.

this keyboard is the best keyboard ever ^^ quite noisy though (the steelseries that I have is much quieter). The model M is the best keyboard i've ever used however, and I pull it out for serious tournments >.>

this keyboard stopped selling because IBM stopped making computers, and terminals fell out of fashion. Mine's from 1987 and still runs amazingly, and I would use mine daily except I have a roomate too noisy for a roomate.



is it an sdl cable?

okay you have me stumped, that's an RJ45 connector on your keyboard, which as far as I know isn't related to the keyboard at all. You'll have better luck getting a SDL to PS2 cable, which is still hard to find. Normal keyboards from that era either have a PS2 or AT (DIN) connector, which you can actually still get adapters for. What year is that keyboard from?

oh...

from this website

Beware of buying IBM model M keyboards intended for IBM TERMINAL COMPUTERS. These have a 5-pin DIN connector or RJ-45 like connector at the end (looks like an Ethernet cable or telephone cable end), but they CANNOT be used or interfaced to work on a PC.
IBM model M keyboards (#1390238 or #25H2142) are for IBM TERMINAL computers and are also clearly labeled as model M, but they are NOT compatible with modern PC desktops
These keyboards usually have 122-keys or 101-keys

the picture matches yours, so it looks like you have an IBM terminal keyboard

He already pointed out the issue.
You can buy replacement cables, sure. Even Unicomp sells them to you, $7 apiece. But they still only work on standard AT and PS/2 models.

But the boards that come with an RJ45 cable don't use AT/PS2 signaling or scancodes. They were made for specific IBM terminals. As in dummy terminals that connected to a mainframe. Like this one:

After you get the cable proper you need the proper driver to manage the keyboard, i forget the names of the programs that do it but i know they exist. just seems like alot of work imo

You could buy a terminal, but make sure it's a smart terminal, preferably VT100-compatible, or else you won't be able to play games like Nethack that require cursor library support, or even use editors like vi.
Try using both Irradiate and Defensive Matrix on an Overlord. It looks pretty neat.
