The Mac 512 has the original 64K Mac ROM set found in the Macintosh 128.  
It supports only 400k floppy drives and the original Macintosh File System 
(flat-file, no folders).  It's also called the Mac 512K or the Mac 512K 
unenhanced.

The Mac 512KE has the same 128K ROM set found in the Macintosh Plus.  It 
supports the 800K floppy drives and the Hierarchical File System 
(folders).  It's also called the Mac 512E or the 512 enhanced.

I believe that these are the only "Mac 512" models ever made by Apple.  
(Of course, I've been wrong before.)  Neither is still manufactured, though 
a 512-to-512KE upgrade kit, which must be installed by an "authorized 
Apple dealer", is still available.

(Then again, remember *who* authorizes the dealers.  Scary, isn't it?!)
