Punched cards didn't have to be readable Hollerith; the maximum storage per card was 80 12-bit columns, or 960 bits when binary punched. The average card is about .006" or so thick by 3 by 8". (About 6700 bits per cubic inch of card; compare that to a CD in its case at 440,000,000 bits/cubic inch.) We still use the cards in our machine shop; they're quite handy for temporary shims, keeping metal parts from marring each other, etc. Ken At 08:41 PM 2000/01/12 -0500, George Woltman <[EMAIL PROTECTED]> wrote: >>At 03:48 PM 1/12/00 EST, Ernst wrote: >>>From a programming perspective, my own top "why 2K" question is this this: >>>even given that the person(s) who first used a mere 2 characters to store >>>the year had good reason (e.g. severely limited computer memory) to do so, >>>why didn't they use those 2 precious bytes as a 2-byte integer? > >I think its due to punched cards.

Recently I installed prime95 on a IBM Intellistation Dual uproc. It seems my combination of soundcard+headphones is VERY sensitive since when I'm running 1/2 prime95s I can "hear" them chugging along on the headphones. There is a low volume high pitch periodic (2/s) noise emanating from the speakers. As soon as I turn prime95 off, it ceases. The volume setting has no effect on it. Has anyone else had this problem? I'm pretty sure its a faulty sound-card, just wondering if anyone had an idea on how to fix it. Thanks in advance. - - ----- I had this same problem too. The solution is to mute the microphone. Don't know why, but it works. - --- - ---------------------------------------------------------------- Get your free email from AltaVista at http://altavista.iname.com _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Sun, 16 Jan 2000 18:09:44 -0500 From: Bassam Abdul-Baki <[EMAIL PROTECTED]> Subject: Re: Mersenne: Re: Setup Testers needed Hi, I recently downloaded prime95 v19 (latest) and I run Windows 98. In the previous version, prime95 used to run minimized when Windows 98 booted up. Now the program runs maximized. Any way I can fix that? Most of the options are grayed out and the preferences, tray icon, and Windows 98/95 Service don't seem relevant. Any ideas on what to do?

Or maybe it was my motherboard. Either way I've underclocked to 400mhz and the problem disappears along with the quake 3 problems. CPU temp went from 139 F to 130 F and mother board went from 97 to 90F _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ End of Mersenne Digest V1 #680 ******************************
