Hardware Requirements:

- You will need a reasonably modern computer with a fast processor. Grav-Sim was developed on a 3GHz Pentium 4 (more than adequate) and has been tested on a Core 2 Duo.

- In terms of memory, 512Mb is adequate on Windows XP whereas Windows Vista users will need 1Gb.

- The GravView viewer works well with all modern graphics cards."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
