As I said a while ago, The 14 yr old that sent the deepthroat trojan (a
trojan similar to netbus or backoriface) to the BEAM listserv has been
warned that if he does something like this ever again, his account w/ his
ISP is terminated.

use between 4.75 & 5.25 volts supply to reliably operate the circuitry.
Even for CMOS 2.8 is kind of on the lower edge.

6427 Wed, 06 Oct 1999 13:20:15 -0600 [alt-beam] MWT Walker video beam@sgiblab.sgi.com Dave Hrynkiw Hi all.
I just posted a 19 second color video online of Mark Tilden's SHOKWalkers,
one that turns, and one that doesn't.
It's a 3.7meg file at 240x180 resolution / 15fps available at
http://www.solarbotics.com/misc/mwt_shokwalkers_1.avi
Sorry it's so big, but I've managed to get it down to 1/2 the size that it
was originally! If I get the chance, I'll see what else I can do to beat it
down in size without sacrificing too much detail.
Regards,
Dave

1/2 the size - 1.58M. Same place, differenct extension.

The program is free and they will tell you how much the boards cost and
