[net.micro.mac] Incompatibilities in Mac 512k's using new LW driver

tomj@oakhill.UUCP (07/11/86)

I believe I have found a problem with using the new (3.1) LaserWriter
drivers on a Mac512K...edit a Draw document, draw a figure using the
polygon tool, print it -- prints O.K., choose smoothing on this figure
and print it again -- crashes the system with ID 02.  This only seems to
happen on 512K's.

Overall configuration is:  15 assorted Mac's (512K's and Plus's), 2 Laser
Writers (not pluses), all attached on appletalk and using MacServe with
about 6 of the Macs (4 Plus's and 2 512k's) set up as servers and the
rest as user nodes.  The servers use a mix of Plus's with Peak Plus30's and
HD20's and the 512k's use HD20's.

The problem occurs ONLY on 512k's using either Sys 3.2/Finder 5.3/Driver 3.1
*or* Sys 3.1.1/Finder 5.2/Driver 3.1.  Haven't tried Sys 3.2/Finder 5.3/
Driver 3.0.  I believe the problem to be one of incompatibility between
Driver 3.1 and the 64k ROMs in the 512k's.

Another variation on the problem is to paste the smoothed figure into a
Write document and print.  The document prints, but no smoothed figure!

Any assistance/ideas on what to try next would be greatly appreciated.

Thanks in advance.  Tom Johnson  (ut_sally!oakhill!tomj)
