Apple II on Raspberry Pi
C’mon let’s all die of dysentery on the Oregon Trail! Update: You probably want to use https://github.com/linappleii/linapple instead of Linapple-Pie these days.
Building and installing the linapple-pie Apple IIe emulator is relatively easy on the Raspberry Pi:
sudo apt install libcurl4-openssl-dev libzip-dev zlib1g-dev libsdl1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev libsdl-sound1.2-dev build-essential git git clone https://github.com/dabonetn/linapple-pie.git cd linapple-pie/src make sudo make install
This also works on an x86_64 Ubuntu machine. It does also install on a PocketCHIP (even if it takes a really long time) but I can’t get the display resolution to fit correctly.

Raspberry Pi Zero: avoiding random network addresses in Gadget Mode
The Raspberry Pi Zero can be set up to appear as one of several USB OTG “gadgets†if you plug it into another computer. The most popular setting seems to be the virtual network gadget that turns your Zero into a computer on the end of your USB cable. Andrew Mulholland’s guide Raspberry Pi Zero – Programming over USB! (Part 2) (along with his super-short simple guide) seems to be the definitive source on how to set these modes up.
One problem, though, is that the Zero would show up on different network addresses every time it was restarted. The changing addresses made ssh access no fun at all. A suggestion on the Raspberry Pi forum helped me come up with a solution. On the Raspberry Pi Zero, run this command once:
echo 'options g_ether host_addr='$(dmesg | awk '/: HOST MAC/{print $NF}')' dev_addr='$(dmesg | awk '/: MAC/{print $NF}') | sudo tee /etc/modprobe.d/g_ether.confThis will set the USB port’s hardware addresses to a fixed value, and you should always get a connection on the same IP address if it’s available.
How my Raspberry Pi Zero appears on my Ubuntu machine Update: For some reason, this seemed to stop working, and I was getting the old random addresses again. I was resisting putting more stuff in /boot/cmdline.txt, but it seems to me it’s more reliable than what I proposed. So if your g_ether.conf looked like:
options g_ether host_addr=66:e0:94:40:44:74 dev_addr=de:82:66:79:e2:66
right at the end of your /boot/cmdline.txt (which is all one line, btw), add
g_ether.host_addr=66:e0:94:40:44:74 g_ether.dev_addr=de:82:66:79:e2:66
You’ll probably also want to share the IPv4 connection so your Raspberry Pi Zero can use the network of the device it’s attached to:
