Totally an interesting, valid machine.

The first-gen iMacs are very limited. However, with major surgery, you
can put quite a lot of RAM in them -- 384MB I think -- and a random
big EIDE hard disk. In that config, they will run MacOS X up to 10.3,
I think.

I find it useful to have G3-era Macs dual-boot, because OS X can talk
to a modern network, read USB mass storage etc., without significant
problems, whereas MacOS 9 struggles.

But -- very important note! It's *ESSENTIAL* to upgrade their firmware
before ever attempting to boot OS X on them even once. Not install,
_boot_. If you don't, OS X resets the screen brightness to minimum --
1% or so -- and it's very hard to get out of that state. You then need
to boot MacOS 9 "blind" and install the firmware update without being
able to see what you're doing.

I've done it. It's tricky but it is possible. I suspect a lot of iMacs
got trashed as "dead" in that condition, though.

But upgrade the firmware first and they run old editions of OS X fine,
and are rather more useful running it and TenFourFox or something,
than they are with Classic only.
