SCREW THE TAPE READING! WHY? JB discovered the catalyst and that process by "Tape Reading" .... didn't he? What else might he/we find by continuing to analyze the tapes that he/we purchased.
It also might not be bad public relations to continue to offer the service, (to Universities, Techs, Government institutions).
There might be a lot of good come out of continued Tape Reading ... besides the revenues.
