   I haven't looked at the schematics yet but I suspected as much.

   What's a Pluto graphics unit? The Sage only comes with512k of memory

    I wonder who finally ended up with his archive? Several people tried to

     Snail Mail! I'll make copies as soon as I get it fired up. I need
backup copies anyway.
