Oops, it's been a while since I last used ResEdit.

Indeed I was pretty sure I would find those icons in any System file/suitcase. But I tried on a 7.6.1 install under Basilisk II just before posting here yesterday, and I could find nothing like machines icons. I guess it was a machine specific install. Anyway, I just took the PB1400 out and found all I needed!

Thanks LCGuy!
