Chuck Peddle was a very effective spokesman and the MOS Technology microprocessors were extensively covered in the trade press. One of the earliest was a full-page story on the MCS6501 and MCS6502 microprocessors in the July 24, 1975 issue of "Electronics" magazine. Stories also ran in "EE Times" (August 24, 1975), "EDN" (September 20, 1975), "Electronic News" (November 3, 1975) and "Byte" (November 1975). Advertisements for the 6501 appeared in several publications the first week of August 1975. The 6501 would be for sale at the WESCON trade show in San Francisco, September 16–19, 1975, for $20 each. In September 1975 the advertisements included both the 6501 and the 6502 microprocessors. The 6502 would only cost $25.
