Hey guys, just bought a Mac SE/30 on craigslist from a professor on a college campus. This is my first 68k Mac purchase in awhile. Anyway, I noticed an "800k" decal next to the floppy drive. I did a little research online and find out there were upgrade kits for SE's to convert them to SE/30's. I'm pretty sure thats what happened here. There is even an SE/30 decal on the back, which looks to be placed directly on top of the original SE decal! See some pics below...

I plan to at least upgrade the memory & floppy drive, and hopefully find an 030 based processor upgrade card. I read I should use "non-composite 30-pin simms" for the memory. How can I tell composite from non-composite? Will I run in to any issues upgrading this mac as it was an SE?
