Yeah, not quite. Just realised it'll take a pair of 512s for a 1GB total.
Got the firmware patch onto a USB stick at a friend's place, updated to 9.1, 9.2.1 and 9.2.2, did the patch, installed OS X 10.3 and updated to 10.3.9. Currently downloading the next round of software updates, the G3 optimised build of Firefox 2, and posting on it in Safari right now.
Another surprise - when I got 9.2.1 installed, it automagically connected me to the net via my DHCP serving DSL modem/router. I thought I was in for manual config hell to get OS 9 on the net.
Also: plays DVDs, has Harman Kardon speakers. Yay.
All in all, I'm glad I couldn't "help myself" when I picked this up last year. This spare, just in case, you never know, oh why not, whim of a computer purchase, which has been sitting unmolested for nearly a year since I nabbed it, is a good 50% faster than the one it replaced. The internal 20GB HD could be quieter - and probably faster too - so I might swap that out for a Seagate at some point, if I can be botherated.
Otherwise, w00t!!
/edit/ Flipping heck, these speakers are good }
