Greetings from Carl Zeiss Inc.
 
In response to recent discussions and questions:
 
1.) "Vendor updates":
        Carl Zeiss has always made software
         updates available at no charge to the user.  There has
         been only one major upgrade to our LSM-310/410
         software.  An announcement
         was sent to our LSM-310/410 users asking
         if they would reply in writing to receive
         the update.
         This helps us confirm that we have the proper
         contact person on our mailing list (often a more
         difficult problem than some might think).
 
         Occasionally minor revisions which are
         essentially
         "beta" versions of the software are available.
         Since these may have unknown bugs caused by the
               modifications
         we do not do a general distribution
 
         A new release of the software will be available soon and
               we will follow the same procedure for its
               distribution.
 
2.) Re: References on published material with the Zeiss Confocal
 
               It is impossible for vendors with a large
               installed customer base to maintain a current and
               exhaustive list of publications.
 
        We do know the applications areas being
               addressed by our users and can provide information
               regarding people to contact for discussions
               relating to details of use of our systems for
               those applications.
 
 
             Two of our users who manage centreal facilities are:
             Dr.
 
               JoAnne Whallon at Michigan State University [and
               is always willing to discuss confocal
               applications] (517-355-0271).  Dr.  Matt Schibler
               at LaJolla Cancer Research Foundation has also had
               pretty broad experience (619-455-6480).
 
   A few recent references:
               Sloane, B. F, et al, 1994, J. Cell Sci. 107:
               373-384
 
               Durfee et al 1994, J. Cell Biol Nov '94 (also a
               cover picture on that issue)
 
               Nishiyama and Stallcup, 1993, Mol. Biol. of the
               Cell, 4:  1097-1108 (NG-2 protein)
 
               Krajewski et al, 1993, Canc. Res., 53:  4701-4714
               (BCL2 Oncoproteins)
 
               To add to our current list we would certainly
               welcome updates
        from our users (or friends).

        Your understanding and explaination are correct.
        One has a choice during data acquisition to store images in the image
        memory (frame grabber memory-the fastest), computer memory or
        directly to the disk (the slowest). In the first two cases to store
        images permanently one has to save them to the disk afterwards. The
        speed depends on the image size (which is selectable) and say for images
        of 512x64 one can acquire 15 frames per second in the image memory.
