Welcome to my Raspberry Pi page. Have a slice. (Also check out my Apple II Extravaganza, if you're so inclined.)
Raspberry Pi Wi-Fi (Pi-Fi?)
Here's some info on how to choose and use a USB Wi-Fi adapter.

Learn how to compile the Raspbian kernel and modules to get Linux components that aren't included by default.
Apple II emulators
I've compiled a couple of Apple IIe and IIgs emulators for easy installation on a Raspberry Pi.
Pi Filler
17-Sep-2023: Pi Filler probably doesn't work on recent versions of macOS. Modern choices to do the same job more elegantly are Raspberry Pi Imager and Etcher.
If you just downloaded your operating system for your Raspberry Pi, you need to copy it to an SD card. Pi Filler makes this super easy and fast. It also works with operating systems for other single-board computers. (You can also use Pi Filler to restore a backup snapshot you made with Pi Copier.)
Pi Filler 2.0.1 adds some new stuff: High Sierra compatibility, ability to use an SD card without having to unmount it first, ability to write a zip file wout having to uncompress it first, enabling SSH on Raspbian, and bug fixes. (29-Oct-17)
download Pi Filler 2.0.1 [for OS X 10.6 Snow Leopard through 10.13 High Sierra]
(source is available by dragging the application into AppleScript Editor)
Pi Copier
17-Sep-2023: Pi Copier probably doesn't work on recent versions of macOS.
Save a snapshot of your Raspberry Pi SD card to a file on your Mac. It's basically Pi Filler in reverse.
download Pi Copier beta 3 [tested on Mac OS X 10.7 and 10.8, but should work on earlier and later versions]
(source is available by dragging the application into AppleScript Editor)
Pi Finder
17-Sep-2023: Pi Finder doesn't work on macOS Big Sur and later. However, it's less necessary than it once was. You can access your Raspberry Pi on the network at the address raspberrypi.local, and you can look up its IP address with this Terminal command: dns-sd -Gv4 raspberrypi.local
If you just booted up your Raspberry Pi, but don't have it connected to a screen and keyboard, you probably want to log in from a Terminal window, but don't know its IP address. Pi Finder figures it out for you, and makes it easy to connect.
Pi Finder also shows you the MAC (Ethernet) address of your Raspberry Pi, so you can add it to your router as a DHCP reservation, meaning your Raspberry Pi will get the same IP address every time and you won't need to run Pi Finder again.
download Pi Finder 1.1.1 [for OS X 10.5 Leopard through 10.10 Yosemite]
(source is available by dragging the application into AppleScript Editor)
