TIME CODE:
REMARKS: An apparently popular early European cassette format. It was the 
first of a family of incompatible standards that used the same coaxial
cassette. See 'VCR Long Play' and 'Supervideo' in the following
sections for details on the derivitave formats. Note that though
this format and it's derivitives had two audio channels specified,
few, if any machines actually used both channels. Representative
machines for this format were the Philips N1500 and N1502. The N1500
was the first true 'consumer' VTR, featuring a tuner-timer. Also, this
machine represented the first use of the term 'VCR'.
