| Thanks to both of you for the info. Here's what I've found:
* Appears that I can do an "erase and install" on my internal disk to restore 10.4. However, I'm too goosey about the next level of side effect surprises (e.g., microsoft software that was updated to fix crash problems) to go that way. i could be much worse off than now.
* I have an Intel dual-core iMac but the system won't let me install the OS on my USB external drive, saying that it can't boot from that device.
If I eventually get a firewire drive I might try again. For now, the operative phrase is Benign Neglect.
Thanks again. Advice was much appreciated, even if I didn't get very far.
