Re: Quad-Port Serial Expansion Board for the Apple Lisa

Hi Ray,

I have some rough steps in a text file, and am hoping to free up some time in the next week or so to work on better documentation. I will post the docs and an image of the SD card to make it easier for folks. WiFi was tricky to get right.

My Pi is a Pi 3 B+ running Ubuntu 16.04 with Postfix to provide the UUCP mail conversion. It’s connected to the QPB using a USB serial converter. Haven’t tried using the GPIO pins. I have a domain whose MX record points to my home IP address, and have port forwarding enabled to ensure SNMP makes it to the Pi.

I will update this thread in the coming days. Thanks for your interest!

James
