I wonder that too, but I don't have any experience using them. Is there
a good (and cheap/free) tutorial/beginner's kit out there somewhere? And
while I have a copy of the LMI lisp sources, I'm not sure about the
microcode and that would be the killer... But that core logic in FPGA
with a modern disk controller, vga compatible video, ethernet and
perhaps USB for the keyboard/mouse? Yeah, that could be a whole heck of
allot of fun...
Oh, for anyone interested, the file referenced above only has the
support (io, disk, video) schematics along with the ai lab paper
describing the machine. The actual cpu and bus schematics are in
