Hardware Voyager Emulator

[Ren]

Just musing...
Does the AtMega have enough memory space to include the software/firmware for all the Voyager series?
I'm thinking something like a keyboard sequence to switch between Voyager models and then keyboard overlays for each model.
I'm also thinking of what it would take to build my own...
(I'm also thinking that some SMD could be incorporated, but that might scare away others from building their own.)
Do you have the Part Number (source?) for the LCD?
Who made the PCB? Would you be willing to share the Gerbers (or whatever) to allow others to replicate your work? I'm thinking along the lines of OSHPark, and how some of their customers share their work for others to use.
I think it could be made into a neat kit (PCB, LCD, CPU, key switches, battery holder, speaker).
But, I don't want to interfere with the possibility of you making a bit of money for your effort, should it be commercially viable.

Of course, I should just keep my mouth shut until you've included the serial port...
