I recently presided over my sister's purchase of a purported Mac 512 KE, used
 (for $800).  It was in very good condition, and I sat down and ran a few
 things to make sure it worked.  Mouse looked fine, etc.  Unfortunately,
 I know next to nothing about that particular halfbreed, and have few questions:

1. How can I tell if it's truly a 512 KE?  I checked its memory under
  "About the Finder", and it showed 512K, but how do I know it's not a
  "Fat Mac"?

2. How can I tell if its drive is double-sided?  I put in a double-sided
   disk, and ran a program from it, but is this guarantee that the disk
   drive is double sided?  How can I tell theoretically, without use of
   a DS disk?

3. After some consideration, I told my sister a Mac 512 KE seemed to me
   to be basically a Mac Plus with only half the memory.  Was I right,
   or are there other differences?

4. What is the last version of System/Finder allowed on a 512 KE?  How can
   I find out?  Is there a Switcher version for it?

5. Will programs in general work?  Say, Word 3.x?  Or will it require
   *really* old programs?  Does it have the new ROMS?  (will programs
   which require those traps, but don't assume a System number, work?)

6. (relatively unrelated) Is there a way to hook up an Epson printer to
   the Mac?  Does Epson make drivers?  Does anyone else?

Thanks in advance,
