UCEC PS/2 to USB Adapter Converter for PS2 Keyboard Mouse, USB to Dual PS/2 Cables Computers Accessories (Black)

Works fine with my Model M. I had a Tinkerboy PS/2 to USB that was working, but one day just stopped registering key strikes. This works fine and the price was much lower. Recommend for old PS/2 keyboards. I will update the review in a few months to see how it holds up.

I have a 1980s-era IMB mechanical key keyboard with a PS/2 plug. This little adapter seems to be working fine, without any missed keypresses or unwanted keypress repeats. Two remarks, though: 1) The USB plug is fatter than I'm used to seeing, and so may not fit next to other (normal width, perfectly flat) USB plugs. You will have to find an unused USB port with nothing next to it. If you don't have one, then order a short generic USB extension cable at the same time you order this adapter and you'll be able to plug it into any available USB port. 2) The PS/2 sockets are a very tight fit. Be patient, look closely, align the cable's keytab with the socket's keytab hole EXACTLY, and push hard. The plug will suddenly snap into the socket. It's a good, secure mate. 5 stars, highly recommended as long as you prepare for the above two oddities.

Working very well with a kvm, sharing IBM k/b with all three computers, use this 4 all PS2 to USB connections, no BS, highly recommended.

Works as expected

I found a 1988 part# 1391401 F2 Model M IBM PS/2 keyboard stored downstairs in an old cabinet. Since these keyboards were built like a tank with tactile touch keys, I decided to try to revive it. I ordered a cheap PS/2 adapter on eBay which failed to function. This one worked well connected to my HP Envy (4 year old) Windows 11 laptop. Very pleased with the results.

I just finally upgraded my 20-year-old PC but needed an adapter to use my perfectly good 20-year-old keyboard. I was told the adapter would cost more than a new keyboard! It didn't take much research by this pretty computer illiterate middle-aged female to prove them very wrong! So glad I found this adapter. Very inexpensive solution and it works perfectly...just plug it in and go!

I bought this to use with an old (but high quality) KVM switch that has no USB ports, only PS/2. I have a new computer with no PS/2 ports, only USB. So I needed something to connect the KVM's PS/2 output to the new computer's USB input. This isn't it. It handles keyboard input just fine, but goes crazy with the mouse. The product description says that it works with KMV switches, but it doesn't work with mine. For people with a setup similar to men, I've tried 4 different converters and the only thing I've found that works is the Perixx PERIPRO-401.

USB to PS/2 Keyboard / Mouse splitters are definitely NOT all created equal. Most are merely plug adapters and not true converters. And of course the vast majority are all simply generically-branded so they are hard to research and have virtually no driver support. This becomes even more of a challenge if you are wanting to use this on a macOS. After quite a bit of research I concluded that this particular unit would indeed work on a Mac. Since there are few brand names I mostly had to go by the picture, and the long (2-inch) thick part on the USB end was indicative of this being an actual converter which is what I needed to get my IBM Model M working on my Macbook. Sometimes it does glitch out and I have to tap the ALT key (mapped to the mac command-key) a few times, but this is pretty rare. TIP: For my 20+ year old Model M keyboard I remapped ALT to command, CTRL to option, and CAPS LOCK to control (very rarely used by anything on the mac), as well as PAUSE and SCROLL LOCK to be brightness down and up. This was much cheaper than buying a modern Mac-compatible Model M-style clicky keyboard from Unicomp ($120+) and I would definitely recommend this adapter over all other generic-branded ones. For PC/Windows users, you could definitely get away with a cheaper-made adapter, but for the price I would get this real converter and know that you have something that will be useful on a variety of computers. I had a couple non-brand and a logitech USB-PS2 adapter, and none of them worked at all for macOS. Even if you don't care about Mac, I've had plenty of USB-PS2 adapters over the years, and sometimes they don't even work on particular makes/models of PCs!!!, so getting a REAL converter like this is just smart.
