Thanks for all the advise. Yes I have Fred's manuscript. I received it from him by mail about 15 years ago (very nostalgic). No criticism of Fred but it's not the easiest read, lacks good organization.

I found myself paging through ATM Book 1 a few nights ago and the RWP drawings of the SHS really brought back memories of my youth.

By the way, Fred's original manuscript along with several updates are here http://www.spectrohelioscope.org/net/

It sounds like a long term build if the parts are gathered little by little or through surplus sources. Some of the designs (lower resolution) really sound fairly simple to construct.

Thank you,
Paul
