removed text: <Drat. This is what Ian Stewart claimed and diagrammed in Another Fine Math You've Got Me Into; but Dahlke's page has a different diagram w/76…that makes 78 much less interesting.>

I moved the below paragraph here from the article:

The 78 RPM record can be in one of two formats. It can be an Edison Disc format, or it can be a Victrola format. Both Discs are about the same size and both have the same size hole in the middle. Edison Discs do not play well with a Victrola reproducer, and Victrola Discs do not play well with an Edison reproducer. This is because the modulation within the groove is perpendicular to that of the other system. The Victrola system uses a side to side modulation or wiggle, and the Edison system uses depth modulation.

This is somewhat wrong in several ways, beginning in that Edison Records discs rotate at 80 rpm, not 78, as do many pre-mid 1920s lateral discs; Edisons are often not considered "78s" by collectors, and if one uses "78" as a catch-all for all pre-WWII systems of discs, there are certainly more than two formats (Pathe Records being the most prominent neither-of-the-aboves). I might try to sort this out in more detail later, but if so it might better belong in the gramophone record article. -- Infrogmation 05:24, 2 Dec 2003 (UTC)

Heptominos moved up[edit]

Since the number of heptominos is a geometrical property (therefore mathematical) rather than a cultural association (the kind of thing the '78 is also' section is used for) I thunk it appropriate to move the heptominos paragraph up and out of the '78 is also' section. -- Anonymous User


Wouldn't there be 364 gifts total in the 12 days of Christmas? (1 on the first day, 3 on the 2nd, 6 on the third...78 on the 12th)?

Prostitutes[edit]

During the 1970s and 1980s some prostitutes took to describing clients who ejaculated quickly as 78s, reflecting the fact those records spin more quickly than others. The slang is now reported to have fallen into disuse.

Does this really belong here? It reads like some sort of bad joke cribbed out of the Urban Dictionary... 217.155.20.163 15:03, 5 November 2006 (UTC)

I moved it here to talk. How common/notable/referenced is this? -- Infrogmation 15:06, 5 November 2006 (UTC)
