Well, I guess it is the same, in as much as both units interface PS2 
keyboards to the 64/128.  However, buying the parts and shipping a 
prototype completed kit to a reviewer in Germany is not cheap, 
considering the HW.  I can do it, but I really want the first units to 
go to folks who can reflash them when folks find bugs.  Ideas?

I saw that.  It's a bummer he (and you) could not get the original C=Key 
code working, but such is fine.  Shame on me for spending so much time 
on this project and not getting it done.
