** this is for the ficticious line eater **

I am looking for technical information on the 1750 RAM module.  I have
seen it advertised locally for $169.  The advertisement said it is
512Kbytes in cartridge form for the C64.  I would like to find out what
the software and hardware interface looks like.

  Does it use a bank switch technique for addressing 64Kbytes at a time?
  Or is it 32Kbytes?
  What address does it use for controlling which bank is active? 

These questions are based on the assumption that it uses bank switching
techniques.

Any information about the hardware and software characteristics would
be appreciated.
