So what you are saying is that the raw keycodes coming from the keyboards that don't work are different than from the spec? 


USB and PS/2 have different values for the lookups.


My raw values were always correct. Hmmmm.

Hi Mark

the problem is quite simple, most of the interface for old machines only 
works with qwerty keyboard
if you buy one  from amazon.fr you will find a ps/2 azerty keyboard the 
signs on the key does not match the result
if you look for a ps/2 qwerty you find some but most of the time mini 
keyboard so small that it's hell to use
and most of the time badly mapped

if you buy a normal size keyboard most of the time it's  a usb keyboard 
with an adaptator
the adaptator + keyboard is just not working

if you try to buy from amazon.com you will find a nice keyboard + extra 
taxes + transport
the keyboards becomes really expensive and you have a high chance to get 
a usb keyboard
with a non working adapter...  (so I don't take the risk)

that's why I'm building my own keyboard interface. I searched for more 
than a year for a solution
I found one, I'll be able to use an azerty keyboard completely localized 
on my old machines

I'm tired of struggling with these ps/2 keyboard and I would have 
preferred to see a usb
connector on Darren's board.
