Hello,
This article will give what you need and good luck with your project. The
information is on the Dux web site. I am a teacher and have had some experience
on this problem; you really have to try them out. IBM keyboards usually work.

What PC keyboards allow for 6-key braille data entry?
This gets tricky. Braille 6-key entry requires a feature called "n-key
rollover". Often keyboard designers leave out n-key rollover to save a few
pennies. So the short answer is some keyboards work, and some do not.
Sadly, vendors change products all the time, and a very subtle design change
can mess up braille keyboard functionality even though the product's model
number may not have changed. Before you pay good money on a keyboard, we always
recommend that you take the particular one you're buying and perform the
following test:
In a Windows computer click Start then Run. In the space provided to type a
file name press the six keys SDFJKL SIMULTANEOUSLY at least seven times. Then
press Backspace to clear the box and then press the six keys once more. All six
letters must show but the order does not matter. If you do not have Windows you
can run the same test at the DOS command prompt. If you cannot get all to show
then you will not be able to braille multi-dot characters reliably with that
keyboard in ANY six-key input braille program.

www.braille-pokadot.com/keyboard.html is a website that gives the model numbers
of keyboards known to work (at one time) as braille keyboards. But remember the
list is just a general guide, also test the keyboard that you intend to use.
