PS-2 / USB Keyboard Rosewill Model RK-9000

I received a nice package in the mail today from K6KX containing a set of keys. The price is not cheap ($99) but they are the best feeling keys I have ever used. They come with two cables, either of which can plug into the back of the keys. One is a normal USB to USB cable. The other is USB to PS-2.

I have not connected it to a USB host yet, but I used it with my PS-2 keyer / kbd for over an hour this afternoon at 67 wpm. This is definitely at my upper end. I believe I can tell a distinct improvement in my error rate.

The key caps have excellent spacing between edges so I am less likely to accidentally hit two keys together.

The keys are mechanical using Cherry switches. They have excellent tactile feedback and plenty audible feedback.

RK-9000 info

They are available from Rosewill through Amazon.

They are also the first set of keys I have had where the output cable plugs in. No big deal, but kind of nice. The dual format (PS-2 / USB) is handy also. All of my kbds currently are PS-2, but I am working on one that uses a small embedded Linux board that will work with USB keys if it ever reaches the stage of being ready for use on the air.
