Beta versions of prism2.device and etherlink3.device (a replacement for 3c589.device) that support PCMCIA cards under AmigaOS4 and MorphOS are now available for download. Thanks must go to Chris McGonagle for testing several versions of the OS4 drivers on a PPC-equipped A1200 as I don't have such hardware.
Be sure to install the provided 68k pccard.library in LIBS:. Further information about installation, compatible cards and contact details can be found in the older prism2 and 3c589 archives on Aminet.
Download here. Please report successes as well as failures - I need to know if the software is ready for a full release.
