So lets have your vote for what replica's of old computers
that need to reconstructed at a functional level -- blinking
lights, mechanical I/O but it need not be the same hardware
level.

I'm biased towards machines that no longer exist, but have
surviving software:
SDS 940
BCC 500
A Xerox Alto using modern components would be interesting
as well. It would easily fit into a medium sized FPGA now.
