How about PacMate braille display?

[Lee Maschmeyer]

The whiz wheels don't always register but should not fail completely. My PAC 
Mate display has always worked well, within that context, including the w h 
i z whiz wheels. Do you have brltty 3.7? 3.6 also worked well, though. Of 
course, the PAC Mate unit itself with the display attached cannot be used by 
brltty. Do the whiz wheels work on the PAC Mate but not brltty or did you 
get only the display?

Sometimes I have to roll a wheel as many as 4 clicks before it does its 
thing, but it eventually does do it. Usually they work the first time, 
though.
