The PDP-8/X
http://surfin.spies.com/~dgc/pdp8x/
"The PDP-8/X is a reimplementation of the PDP-8/I, with 32K words of memory
(all the memory you can put on a PDP-8/I), an extended memory control, an
interface to an RS-232 terminal, and an interface to an IDE disk."
Looks kinda cool. He mentions in a posting that he'll post the XILINX code
in a few days.
