If you think it isn't, you're either too ignorant (or obstinate) to understand where it went to or came from. My post: "How many Coulombs can a 1mH inductor charged to 1A deliver?" was meant to elicit (�) some thought that would help lurkers understand that. Instead it elicited obnoxious responses, even from the resident PhD. 'Tis a shame :-( (�) For "markp", the resident illiterate ignoramus: http://www.merriam-webster.com/dictionary/elicit ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Spice is like a sports car...

That name brings back some memories. Used to >love rooting around there as a kid. Yep. Also Olson electronics stores, and mail order from Allied Radio (Knight Kit!) and Burnstein-Appelbee and more; Newark electronics will call (call them up, order, and show up with cash, at age 14 they thought you were a runner for dad's shop). One of my bigger surprises was getting uA741 op amps (mil overruns and other surplus) at a surplus house in Mountain View for $0.50 each in the mid to late 1960s. And Motorola, NS, GE, RCA, TI, Fairchild and other semi. mfgs. making all kinds of experimenters kits. Growing up in silicon valley was great. |
