I think this is a wonderful idea, sort of extending on what MJM
brought up earlier.

I don't see any reason why Alex & Steve's FPGA implementation of the
Apple //e could not be modified to implement such a system.  The limit
on the number of //e systems would be the number of gates on the FPGA.

Good points.  I'd enjoy this too.

I'm looking at an Altera Cyclone-3-based system with an extra board
that has a color LCD touchscreen on it and supports VGA+USB+CF
+ethernet as well.  Price is around $450 which is a lot less than the
dev board Alex & Steve are using.  The downside is that it would not
(without some additional hardware support) accept Apple II cards to be
plugged in.  In any event, if the system were to be portable (and
these cards are quite small) and battery operated, that would be
precluded anyway.

Yes!

I have no interest in making this a business.  This is my hobby and
I'm just happy that there are other people out there with similar
interests I can share it with.

If you're limited to the $200 price range, there are other FPGA dev
boards by www.knjn.com which may interest you.  Check out the Xylo-EM
which has an Altera Cyclone II FPGA + VGA + Ethernet (10baseT) support
on it all for $129!
