You guys are in luck, I just happen to have Bob Beck's paper on the
construction of SRD. It was published in 2 Aug. 1978 and is about 30 pages
long. Beck also wrote a number of articles in Borderlands mag but I can't
find them in their archives, assume it was some time ago. If any of you are
interested, I can send a copy if you include a self addressed (8"x11" if
you don't want it folded) envelop plus copying and mailing costs (say $5-6)
from Canada. Or I will exchange it for some of the Borderland articles
related to entrainment by Beck. I have also built a variant of his Brain
Tuner can direct you to info on that if interested.
