Some keyboards cannot boot into Open Firmware on the blue and white G3s

If you want to access Open Firmware at startup, rather than the boot the Mac OS, type Command-Option-O-F. This is not something most users will ever need to do. However, if this is of relevance to you, a new TIL article (#58248) notes: " There are some ADB AppleDesign keyboards which do not properly signal the Power Macintosh G3 (Blue and White) to enter Open Firmware during startup. The AppleDesign keyboard has the ADB cable hardwired to the keyboard. The specific keyboards which cause this anomaly are those which have a stepped Caps Lock key and say "AppleDesign" on the underside of the keyboard. The solution is to use the USB keyboard which came with your computer, or a different ADB keyboard to boot into Open Firmware."
