fyi: the 4.3bsd quasijarus tape file can be found here:
http://www.retrocomputinggeek.com/retrowiki/Install4.3BSDQuasijarus/
along with instructions. (I could swear the person who's website is on
this list, btw)
and if anyone is bored, I have an "expect" script which automates the
whole thing. This comes in handy if you are going to do it a few times
for different size disks.
