Practical Electronics and D. Bollen

Hi, I'm looking for information about an author (and a series of magazine articles he wrote in the early 70's concerning analog computers) by the name of D. Bollen. The articles might have been published in "a popular English `do it yourself' electronics magazine called something like Practical Electronics". Does anyone have a near complete collection of Everyday Practical Electronics (EPE) Magazine? Maybe the magazine has an author's index. Can anyone think of the name another similar magaazine that fits this description? I've been told that these articles contain the "Full details" of my C180 english analog computer. Regards, --Doug P.S. If you CC me then I don't have to wait until tomorrow for your reply. :) ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://www.best.com/~dcoward/analog =========================================
