He told us that HP35's were prime deal-making fodder with the managers who'd sign over their first-born to get ahold of one. I computed a LOT of ECPs (estimated critical position) for reactor startups using it, and it because a ship-wide computing resource because we had nothing on board that was remotely as powerful. All the computers were either analog, often using syncros and servos, or had 40 WORDS of digital program storage. A few years later, in college, the HP sales rep told me it was madness for the first year. An early HP35 was worth its weight in gold to open doors and engage in conversations that ultimately lead to discussing things of real import - like scopes and test equipment. It was an amazing product and would have defined "geek" if the term existed then. On 12/7/05, Frank Dernie <Frank.Dernie@btinternet.com> wrote: > I am an HP fan too.
