Sentry projects in Elementary Electronics Magazine.
While cleaning out this weekend, I found a small collection of
printed circuit boards that I got from Elementary Electronics 1967-68. They're not really worth anything, but it would be fun to know what they are. I can't find them using Google. The dates are scratched on the boards and the names are part of the etch. 1: Sentry Multivibrator, May 1968 2: Sentry Lo-Frequency Oscillator, March 1968 3: Sentry Hi-Lo Bander, July 1968 4: Looks like a wireless mic, no name (has 9V, ANT, SW and MIC on the etch), Sentry, Nov 1967 These were distributed via blister pack (IRC). Just curious. Steve. -- Steven D. Swift, , http://www.novatech-instr.com NOVATECH INSTRUMENTS, INC. P.O. Box 55997 206.301.8986, fax 206.363.4367 Seattle, Washington 98155 USA |
