Adaptor for a circa-1987 IBM keyboard.

All I can say is that it works as intended. That's not always the case with Amazon. Ha!

This works much better than the last PS/2 adapter I used (over 10 years ago). I'm not sure, but I believe this is an active adapter.

I am mainly a PC user but recently purchased a 2020 M1 MacBook Air. I've been using my trusty IBM Model M1 keyboard since 1994 and wanted to keep using it. This converter works fine when it and my Mac were plugged into my USB C dock connected to the Mac Thunderbolt 3 port. Upon plugging in my keyboard, I did need to go through a quick setup process after it autodetected the keyboard.

The caps lock button works fine and lights up in the upper right corner, but the Num and Scroll lock buttons do not work.

BTW, I did try a different adapter from eBay that was a 2" USB/PS2 plug in one (no wires), but that did not work.

Overall, this converter rocks!

This is what you want. CONVERTER. Have an old keyboard that I really like, new CPU does not have the PS/2 socket. This converter lets me continue to use my favorite keyboard. Thanks.

Actually works (as opposed to some brands CLAIMING to provide a connection but not working).

Works as stated. Good job.

This worked in extending an old styled keyboard to a usb port.

I ordered this to replace a 13 year old failed adapter. It performs as expected. Competitive price and terrific customer service!

It is indispensable and allows built-to-last input devices to be used on modern computers. It would be considered no-frills, but I see it as exceptionally reliable. Many other adapters encounter random restarts, or delayed reaction times (probably due to a power save mode). I love this, and hope it lasts as long as my quality older input hardware!
