Ah! I thought that red light was weird, never saw it on my SE.

I'm pretty certain that it has the 400k drive, as it won't read any of my 800k disks.

I'll hold off on opening it for a while and just live with the RAM... though it is nice to see it's something reversible.

I bet the guy I bought it from spent quite a bit of money upgrading the RAM.. who would have thought 10-15 years later that people would be actively trying to oust it?
