It may have larger dimensions than "portable" VCRs, but it's not really cumbersome, and its weight is low enough that I consider it as portable as any piece of audio/video equipment I have. *And* it has Hi-Fi! > As an extraneous comment, I'd like to blast the person who said that > Beta technology has been haphazard.

Perhaps he/she was thinking about the bizarre L-830 which > pushes BIII to 5 hours. But the L-830 is just as simple a proportion as the L-500 or L-750! At Beta-II, it yields 2n minutes, and at Beta-III, 3n minutes, where n=100. And the ratios of the numbers to tape lengths (in minutes) is the same: 830/500 ~= 200/120 830/750 ~= 200/180 750/500 = 180/120 (all time figures are at Beta-II speed). The numbers 500, 750, and 830 are derived from the length of the tape in feet. A good reason for the L-830's existence is that many movies are ~100 minutes long, so a tape length in 100 minute increments makes for optimal tape usage. --- jayembee (Jerry Boyajian, DEC, Maynard, MA) UUCP: {decvax|ihnp4|allegra|ucbvax|...}!decwrl!dec-rhea!dec-akov68!boyajian ARPA: boyajian%akov68.DEC@DECWRL.ARPA
