Re: Maxtor full-height 5.25" drives of death

Any idea if the drive orientation during storage might make any difference in the failure rate? Usual PCB side down, PCB side up, either side down, either end down? My guess it that it is best to store them in the usual PCB side down orientation, but that is just a guess.

Intel 8085 - interview?

At some point I read an article or a transcript of an interview with an Intel employee (or former employee) who had been involved with the design of the 8085, describing how he had specified additional instructions over those of the 8080, and they had been implemented in the silicon, but then the

Although, it may seem that the heat while running can't effect a stored drive, heat is still a major contributor to such failures. Heat causes the seal on leads to fracture. While sitting on the shelf, moisture and other atmospheric contaminants get to the silicon inside. Most silicon has some
