Average Reviews:
(More customer reviews)I'm one of those IBM Model-M "clicky keyboard" people. I won't use any keyboard but an IBM Model-M.
Unfortunately, the Model-M keyboard uses a PS/2 connection and does not interface to newer USB only computers.
So, an IBM keyboard user needs a PS/2 to USB adapter.
There are adapters out there which simply cross the wires. These DO NOT work with the Model M.
There are adapters out there with an active controller chip in them which (supposedly) properly converts the PS/2 signal format into USB.
Now, here's the big point... the PS/2 protocol is bi-directional. That is, the keyboard sends signals to the computer, BUT the computer can also send signals to the keyboard (such as "turn on the num lock lamp" or "do a reset").
I've tried every active controller that I could find with my Model M keyboard.
NONE of them sent communications back TO the printer... except the Adesso adapter.
The Adesso adapter sends all data transactions between the keyboard and computer... in both directions.
I was using a different adapter before and had random problems such as no reset (I had to momentarily unplug the keyboard) and the worst problem was multiple keystrokes.
Sometimes it would do thissssssssssssss
