These might be of interest to someone here -- I have run across the Service Manuals for a Radio Shack CT301 "brick" cell phone, for which I have no use. It's got schematics and parts lists, theory of operation, and other interesting information and dates from 1988.
I may actually have the 'phone around, too.
Please contact me if you're interested in this as a relic of a bygone age.
