Noise signal from the past

Audacity 2.0.5 under Windows XP Home
I have a recording with the filename 'Audacity triangular white' made in 1997. It is different from the white noise generated by 2.0.5 in that it has a triangular amplitude-probability distribution (APD) whereas 2.0.5 produces white noise with a uniform (rectangular) APD. Can anyone remember this 'triangular' noise and whether it was intended as a dither noise?
I think there should be a mention that the APD of the 2.0.5 white noise is uniform and not Gaussian. The pink noise IS Gaussian.
