I think that skirts the appeal of a *real*
"miniture PDP".
E.g., why not just do the whole design in an FPGA? It would
be a pretty boring accomplishment.... :-(
Huh? I don't think so, at least not for me. I'm totally in love
with my SBC6120, which is at least a move in that direction. I can
run it 24/7 and just have it available on a serial port which I can
get to when I'm not home, for some OS/8 hacking when I get the itch.
But, you can make the move all the way "in that direction"
and just run an emulator. :> I.e. the appeal is having
the actual hardware. And, while PDP's are reasonably
commonplace, having a *tiny* one (imagine a 10x10x10 8/i
sitting on your COFFEE TABLE :> ) would be truly unique.
If you're going to build a miniature system out of modern components,
why not just use a FPGA? :-)
