Checked in on my #globaltalk setup that was working fine yesterday, but this morning is completely borked. Globaltalk Zones disappeared in Chooser and no file servers in local Zones in Chooser on my Mac Plus.

Restarting jrouter, netatalk, tashtalk (in that order) had GlobalTalk zones come back, and while my EtherTalk zone (Vermilion Sands) showed up in Chooser, my LocalTalk zone (Vermilion Sands LT) does not.

Looking at the jrouter and tashtalk logs there are errors which seem to point to a physical layer problem if checksums aren't matching?

Timing is jrouter got an unmarshaling error (15:19), tashtalk then gives a invalid long DDP header (15:21), then jrouter drops stale buffered packets (15:22).

tashtalk:

2025-04-16 16:21:51,014 DEBUG: tap0 failed to parse AppleTalk datagram from EtherTalk frame: invalid long DDP header, checksum is 0xD42F but should be 0xD22
A

jrouter:

jrouter-1 | Apr 16 15:19:50.440 ERR ZIP: Couldn't handle packet device=br0 error="ZIP GetNetInfo Reply unmarshaling unimplemented"
jrouter-1 | Apr 16 15:22:08.728 WRN EtherTalk: dropping stale buffered packets device=br0 dst-net=1971 dst-node=135 drop=1

I've finished writing up the guide for building QEMU version 9 on a Raspberry Pi 5 along with the scripts to enable bridged networking for AppleTalk over Ethernet. The guide covers both 68K and PPC Mac emulation.

Hope you find it useful!

A screenshot of a Raspberry Pi desktop showing three emulated Mac desktops in windows. The top left is System 7.1, the bottom left is System 7.5.5. The top right is Mac OS 9.1. All three are showing the Chooser open with the AppleTalk MacPalette II driver selected. They're all showing that they located two ImageWriter II printers on the network. A web browser window is open behind to my blog biosrhythm.com.

Greetings to the retro computing community. I found an old EtherPrint bridge. I last used it 10+ years ago to connect a LocalTalk printer to an Ethernet network and Mac OS X. I would give it to good home for shipping (from Switzerland).

Does anybody have a #LocalTalk or #EtherTalk module for a #StyleWriter 2400 that they aren't using / don't want? Either Apple or third-party would be fine. I'm sure we could come up with something to trade for it!
