Oh no, tape drives were doing hardware compression well before 1995.

The good news is that the cost to upgrade has continued to fall too. You can get a complete system (with monitor, printer, and even a frill or two) for under US$1000 these days; I remember having paid twice that for a 105Mb disk drive some years back :) If performance keeps doubling every few years while total cost for a "cutting edge minus a little" system continues to fall, I won't be too upset. -- Jon Hamilton hamilton@pobox.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
