Ooh, if 7.1.2 works on my PB 145 I'm interested. 
I just started it up (with headphones... in case anyone hasn't tried starting a Mac with headphones before, it's loud!) to check and it doesn't say what version of 7.1 it's running so I could do 7.1.2 and still be original to the best of my knowledge. 
Took a look at the Garden and found a bunch of software, just need a floppy drive and to find out if my Mac-formatted floppies from 2005 that I never used are still any good.
