Arthur,

I'm considering to buy some of this displays for other projects (even 
change the micro family), as they have a nice cabinet that sometimes is 
the most difficult part to build.

Could you tell us if they use a common LCD connected to a pcb with the 
micro, like the Didier design or these are fully integrated in a single 
pcb?  Any picture of the inside would be very appreciated.

Best regards.
Ignacio, EB4APL
