You need a copy of the FCC 79-555 report and order of 1979 implementing
the regulation of digital devices. Appendix C is titled "Derivation of
Limit for Class B Computing Device". The class A limit was derived from
CBEMA proposal CBEMA/ESC5/77/29 which was also submitted to CISPR. I
would be willing to send you a copy of an exerpted FCC R&O published in
Dash's 1984 annual if you send me your fax number.
