OK. Trying to put together a 'puter for Grannie. Something cheap (means on hand) but up to date. I think Ubuntu Linux will be the solution. The second beige G3/233mHz/192mB desktop was choking on OSX, so I formatted and did a clean install of OS9.2.2 from the eMac disk Mike got me. It runs, but that is a slooooow machine in Classic, and is almost completely unsupported with up-to-date browsers and mail clients.
BTW, Mike - Apple has a tech sheet that says the grey screen with the refusal to go to Open Firmware is the result of upgrading the beige G3 to a hard drive larger than 8gB and then downgrading again. Takes some fiddling with the PRAM to restore it.
Downloaded the Ubuntu 6.06 (Dapper Drake) .iso file and burned it to a CD. Found out that the beige Macs are "Old World" and will not live-boot Linux without a resident Linux kernal. Downloaded BootX and have to burn a disk to transport it from the G5 to the G3, since the G5 has no floppy and the G3 still is not networked.
From all indications, I will have to reformat the G3 hard drive and partition it, then reinstall a minimal OS9, add the BootX, and create a Linux Kernals file in the System folder. At that point, from what I have been reading, the Ubuntu CD should live-boot. That's what I get for being cheap. "New World" Macs live-boot the Ubuntu CD straight out of OSX. So do the Intel/AMD based machines (and if I could scrounge an old Winders laptop from somebody's roadside trash, I could have a modern go-go-'puter!).
The Ubuntu CD comes packed with the whole system and applications -- Open Office, Thunderbird, and Firefox included -- and a desktop that looks and handles like XP. All I will need will be a PCI modem card and a video card with S-Video out (Grannie will need to use dial-up or DSL, and her TV is bigger than my 20" screen and has an S-Video port -- might be easier for her to see). I saw a Radeon 7000 card on eBay for a buy it now price under $40.
Once that is running, I'll have to put something together for Mix. Jesse still has that 6400 and he isn't using it; it should easily run the same Ubuntu release.
