I use a PS2 to USB adapter. You can easily find them on Amazon and eBay. Mine is this: https://www.amazon.es/dp/B008DFVQFW/ref=cm_sw_r_other_apa_i_IVrCEb56SDM4W

That’d probably work for it

It’s a PS2 to USB adapter/converter on Amazon. I’m just grasping at straws thinking that I can find an simple solution to my problems. 🤫

That one presumes you have a keyboard which can do USB., for that is jut a plug converter.

Instead one like this is called for, because that can work with the oldest PS/2 keyboards (I have one, and used old AT keyboards with an AT toPS/2 plug adapter), because the blob in the cord has the smarts to be USB.

Or just get a modern USB keyboard.

What’s the misinformation you’ve already encountered (so that commenters not perpetuate frustration points)? Hopefully this won’t be one of them. Are you using an active PS/2 to USB convertor vs. a passive passthrough adapter? https://www.amazon.com/Perixx-Adapter-Keyboard-Interface-PERIPRO-401/dp/B008DFVQFW/ (I’m assuming the “Built-in USB IC” in the description means it has the active circuitry to translate PS/2 protocol to USB.)

If it looks like there are some electronic components inside that’s an active adapter. For example any of these (Amazon links):

>If it requires Arduino and/or soldering don’t bother though. Goes over my head. Thanks anyway.

No, not at all! Converting PS/2 to USB is a simple process, it’s just manufacturers of adapters tend obscure whether their adapter is passive or active. I’ve found that adapters that offer both keyboard and mouse inputs at the same time are usually active since the adapter has to do some processing anyway (to send two signals through one port), so it kills two stones with one bird. Also, ones that are very bulky or are transparent and have visible chips inside tend to be active too, and technically speaking, a passive device should be labelled “adapter” and an active one labelled “converter” but not all companies respect that distinction. Anyway, the problem is that since 1996/97 when USB took off, supposedly PS/2 keyboards these days can send both PS/2 and USB codes out, so a passive adapter that simply runs wires between the different pins is usually good enough. For anything older, this isn’t the case.

And don’t worry, none of these converters requires assembly nor do they need a mouse connected at the same time to work.

I currently use two converters; a Perixx PERIPRO-401 and a Soarer’s Converter. The latter is my recommendation since it’s cheaper and just works. As they advertise on their website, the converter has “Built-in USB IC” so that it can translate PS/2 to USB. I got this converter bundled with a Model M in fact, but it goes for about £13.94 on eBay UK or just $6.99 on Amazon US.

The other converter also just works simply if you want it to, but it’s a bit more advanced in that it can be programmed to remap keys and add macros to the keyboard without the need for a software client. Basically, Soarer’s Converter is a widely-used tool in the vintage keyboard community to add a lot of functionality to old keyboards whilst keeping those functions portable at the same time. So if you think that you might be wanting macros and willing to learn a bit of scripting (it has its own fairly-simple language) to set them up, you can pay a premium for one. It’s my preferred converter because it allows me to take advantage of the abundance of keys on some of the keyboards I have.

Here are some more simple active converters I’ve used in the past, but they don’t get my absolute recommendation since they’re less durable than the other two nor do I know if they’re available in other countries.

  • zdyCGTime – £6.99, very cheap but you have to be careful with it – mine snapped in half
  • Ruibo Sike – £12.99, very similar to the Perixx but feels cheaper IMO

Hope this helps! Any other questions, just ask!

If your Model M has a PS/2 (min-DIN with 4 or 6 pins) or AT (big DIN with 5 pins) plug, you can buy a PS/2 to USB active converter from Amazon, eBay or even some stores. The perixx PERIPRO-401 is a well known cheap option known to work with Model M keyboards such as your Enhanced Keyboard, available on Amazon US for $6.99 and Amazon UK for £4.99. For an AT plug Model M, you can use this same converter, but you’ll additionally need an AT DIN to PS/2 DIN passive adapter, which can be bought on eBay US for ~$4 and eBay UK for ~£2.

That’s full-size DIN used for XT and AT keyboards. The keyboard itself is an AT keyboard (PS/2 is basically just an AT connection through a smaller plug), so in addition to needing a PS/2 to USB converter, you simply just need a passive DIN to PS/2 adapter too. Below are examples of both I own and know to work fine:

I appreciate these on UK sites, but I’m sure you can find these or something similar in whatever region you’re in.

I think I’ve seen this one recommended, but don’t have any personal experience with it:

https://www.amazon.com/gp/product/B008DFVQFW/

If you’re willing to shell out more money, you can go for a Soarer’s converter and basically be guaranteed a flawless experience.

This one would work, in conjunction with a 5 Pin DIN to PS/2 passive adapter:

https://www.ebay.com/itm/302711725609

Normally the same seller has a PS/2 version as well, but it’s out of stock at the moment. No functional difference, just a different plug.

The Soarer’s converters support full N-key rollover, which Model M won’t give you anyway, but the point is that you won’t be limited by the converter. I use the Soarer’s linked above with my Model F and it’s been flawless for over a year and a half, even with gaming that involves all kinds of key combinations.

That’s fantastic information, thank you. I’m in the UK (I had the keeb shipped from the states). Is this the badger you talk of here?

If you want something that justs works, I’d recommend the Perixx PERIPRO-401 (£4.99 @ Amazon UK, $6.99 @ newegg US). It’s what I’m using to type to you on with my Unicomp Model M4-1. Converters like are very generic devices though, so a lot of them really look similar or exactly the same. The typical signs that they are what you want include:

  • Being labelled as an active converter (passive adapters will not work with many older PS/2 keyboards in general)
  • Being labelled as having a USB integrated controller (IC)
  • They have a box in the middle of the wire (although exceptions exist)
  • It’s a dual keyboard and mouse converter (although exceptions exist)

If you don’t mind paying a little extra and would potentially make use of features like remapping and macro support without requiring installed software, a Soarer’s converter by orihalcon for $39.99 is a great premium option. I have three for different IBM keyboard types and they all run fantastic.

Would it be ignorant to think I could wire the original five-pin cable into this adapter?
