Yes, 768 MB of RAM. I’m very impressed with it. I’m also very impressed with FedEx; I ordered it from Crucial on Friday afternoon and got it about a half an hour ago. It’s already in there.
Just FYI: the system, under Mac OS 10.2 (my main system that I do almost everything on) had an uptime of 32 days, 14 hours. Rock.
(and the fonts and Lurk work again! w00t!)
