Transforming a Mac 68k program into a Linux Daemon
The Insentricity blog dives into turning an emulated Mac 68k program into a Linux Daemon:
Just a few days before the end of #MARCHintosh a call went out over Mastodon asking if anyone had an Apple IIe with an Apple Workstation Card. The hope was that someone could try to use it to join the #GlobalTalk network. While I have the hardware required, I had been reluctant to try and participate in GlobalTalk. Joining GlobalTalk required using a very old program called Apple Internet Router which only ran on System 7.1 on 68k Macs.
The decision was to use an emulated Mac via QEMU in a Linux Docker container.
Getting TCP/IP working wasn’t so simple. It turns out that even though QEMU had been configured for bridged networking, absolutely no TCP/IP traffic ever seemed to pass to or from the emulated Mac.
I found a command to tell iptables to stop dropping traffic going through the bridge, and suddenly the emulated Mac was responding to pings! Moments later @wotsac was able to see my netatalk server being routed over the internet! My emulated Mac running Apple Internet Router was working!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
