I'm not too sure how many others out there are stuck with 3/75M-8s, but 30% of our clients are 3/75s and they fail (power supply mostly or the motherboard goes from overheating) a couple of times are year. This was compounded by Sun restricting the repair timeframe to only making the 30 day repair available. It seems that the problem with these units is a weak (and poorly designed) power supply and poor ventilation. It sure would be nice if Sun would be magnanimous and say "hey, we made a mistake . . . " and give 3/75 owners a good deal on upgrading to a 3/160 housing. Others at this university have taken the CPUs and memory boards from 3/75s and put them into housings for 3/160s (the 3/160 boards where put into cages on mobile robots,etc). Our 3/75s spend almost 40% of their year being repaired (unless you want to pay around $1000 for a new supply or $600-$800 for a quick turn-around repair). When I queried the people at the (800)USA-4SUN number they told me I should rid myself of the 3/75s and purchase 3/60s. There isn't anything wrong with the CPU, memory board, or monitor - it is just a @%!$@$#$ enclosure. If you are going to upgrade the donkey 3/50 why not save us 3/75 owners?
