We were able to load DECnet for Macintosh 1.0, and use NetCopy to transfer files from a VAX to our Macintosh without any issues. We also used DECnet for Macintosh 1.1 EFT1 and that also worked fine.
We used a Macintosh IIfx, running system software 6.0.5, 4MB RAM, and DECnet for Macintosh 1.0. Our EtherTalk software was installed from the EtherTalk Installer version 2.5.1 that came with the Apple Ethernet NB Card. The other EtherTalk components and versions are EtherTalk Prep 1.0, EtherTalk Phase 2 version 2.2.2, and A/ROSE 1.1.4.
To troubleshoot further, answer these questions:
- Did this happen on every system? Could you try other systems?
- What is the hardware configuration of the Macintosh?
- What are the system software and network software versions?
- Did you try on more than one Apple Ethernet NB card?
- Do you have any INIT or CDEV, which might conflict with Apple software or DECnet software? You should try with a clean system.
