[comp.sys.mac] More on the Mac 512K and LW 5.0 Problem

More on the 512K, KE; Laser Driver 5.0, and Systems 3.2, and 3.3.

To date I have received only the following message, on our problems with
512K's and Laser Drivers (LDs) 5.0.

     From:     <ELFJ%CRNLVAX5.BITNET@CUNYVM.CUNY.EDU>
     Subject:  Laserwriter 5.0 bugs
     
     We have also had problems with the latest version of LaserWriter
     and LaserPrep, but they stem from using them with System 3.2 on
     512E's.  When trying to print a non-laser font, system crashes may
     occur that permanently destroy the disk.  We've had both system and
     data disks go bad and thought all our disk drives were dying until
     we diagnosed the problem.  Problems occured with Word 3.01 and
     MacDraw, but not Word 1.05 or WriteNow.
     
     Our only solution was to go to version 4.0 of laser files.

In the meantime, I contacted Apple Canada, whose first and immediate
response was to go back to LDs 4.0.  Stating that this response was
unsatisfactory, and that the documentation for the v5 System Software
specifically states all machines on an Appletalk must run the same LDs,
they said they would inquire to the US.  The following answer was
received (as best as I could transcribe the voice answer):

"The LDs 5.0 were designed to function correctly ONLY with machines
containing one or more MB of Ram.  There is no simple cure that would
allow this driver to work properly with the 512K Macintoshes, regardless
of 64K or 128K rom.  We will inform engineering that we have clients in
the field requesting a compatible driver for Mac512K machines".

This is a partially satisfactory answer, but we still cannot upgrade our
512K macs at the moment at the current upgrade prices, and our users
really do prefer LDs 5.0.  I wonder how many Macintosh Environments are
being hurt with our problems, and the ones mentioned by Linda Iroff.

Well, I wish I could talk to someone in Apple USA, as my call to
Public Relations got transferred to  International Customer Relations,
and they have yet to return my call.

Come on, Apple, there are some of us out here in the world that once
believed in you for your upward compatibility and your upgrade policies.

Unfortunately, the enhancement from version 4.0 of the LaserWriter
drivers to 5.0 and the introduction of background printing for
Multi-Finder, finally pushed the operation of the driver beyond the
limits of the 512k Macintosh.  This was somewhat unintentional
because testing which had been conducted on 512k systems seemed to
work.

In any event, we are in the process of correcting the 512k problem
and hope to have a workable solution when version 5.2 is released.  
Even so, the 5.0 version is still going to be more memory hungry
than previous versions and developers ought to be aware that 
arbitrary fixed allocations for free memory during printing is
perhaps not a good idea.
