ok, we shouldn't discuss this subject on the list, but.... 1) The 3705 *always* has regulated voltage sources problems. But right, it is overheated. 2) The air-conditionning system is not strong enough, we know it. I'm not responsible for the stupidity of the Head Directions which states that it is enough for the machine, period. Never argue with God. 3) We're not going to buy a 3725 but a 3720. We don't want to buy it. However IBM has prepared a neat 'cle en mains' system for us, with everything as THEY think is best and they said it would be real nice. The Head Direction trusts IBM and says sure, it will be perfect. Except the total disk space will be only 1/3 of what we have at present, but "just ask the users to reduce their disk usage". It's nice, all we have to do is sign the check, and since the people who sign the check are satisfied, all's well that ends well. 4) However: two 3375s and one 3720 heat less than 16 3350s, one 3705 and one 3211 (we won't have any line printer on the new system). So the air condi- tionning system will be relieved of a lot of heat and will probably become too strong. I've been trying to suggest that the temperature regulator be repaired before installing the new system, because then it will perhaps not be desirable to have the thing work 100% of the time, but without success. We've already had ice in the room once, after having powered off the compu- ter for three days...... Eric
