I had to calculate it myself using information from ddcheat.

Edit:
Structure for LCD signs:
short magic;
short size=1C00;
long id=3C00 0000
short xStart; //Left
short yStart; //Top
short xEnd; //Right
short yEnd; //Bottom
short messageIDGreen; //0 to display only red (joke) messages
short unknown;
short messageIDRed; //0 to display only green (instruction) messages

Edit 2:

Portals:
short magic;
short size=2400;
long id=1C00 0000
//x%25=1
short x;
short y;
short x2=x+24;
short y2=y+24;
short direction;
short unknown;
short unknown;
short unknown;
short unknown;
short background;
short type; //0 is stay open, 1 is rescue, 2 is shrykull, everything else is glitchy (yet funny)
short shrykull; //number of muds for shrykull
short unknown; //these probably deal with stay open portals
