Why don Parallax drivers version 3.06 work properly on my SPARCstation 5 or SPARCstation 20?
Parallax drivers version 3.06 contains some incompatibilities with the Parallax device drivers and these models. Version 3.07 fully supports the SPARC 5 & 20. Support for SPARC 5 audio is included in this release, but only for Solaris 1.1.2 (SunOS 4.1.4). If you have a SPARC 5 with Solaris 1.1.1 (SunOS 4.1.3) or earlier, you must upgrade your operating system in order to take advantage of this feature.
