Pretty slick!
I have a PowerBook 145 myself and did a bit of tinkering recently to run
ConfigPPP on it. I forget off hand what files I had to take off my other
Macs to get it to work right without totally upgrading the OS.
I use it alot as well, taking it with me on trips and to conventions. It
is loaded down with alot of early software versions, kind of like a
functioning library of old versions of popular software. Hell, IRCle
0.4.7 runs just fine on it. :)
