I think it's to be expected since the power supply is right under there; according to some early information on the power supply, the first machines (including the present ones, I presume) used a conventional, non-switching power supply due to some problem Apple had with getting the switching power supply out in time. If so, that would explain part of it, since I think it would tend to get hotter than a switching power supply would. In any case, there's a note on page 135 of the plain User's Manual in the section entitled "keeping it in good shape/main unit" which says "The top of the main unit will feel warm to the touch (about 85 - 90 degrees F.) after it's been on for awhile." Right now as I write this, mine has a temperature of 102 degrees F. measured by putting a desktop thermometer face down on top of the left vent until it became stable. That's with a room temp- erature of about 78 degrees. -- Eric Roskos jer%vanderbilt@csnet-relay
