It looks like @Dronecatcher provided the answer for this one already.https://support.apple.com/kb/DL1192?locale=en_GB
The System folder can be copied to your HDD and Classic will find it upon activation (Prefs panel).
If you read the instructions, you'll see there's a default user login with this - to bypass, before activating, go into System Folder/Extensions and delete the Mult-User Startup file.
Nice solution! I clearly misread the part about booting into OS9 and thought you were running under Classic.I finally figured it out. Although I was setting 640 x 480 in Classic preferences, it was changing back after the Welcome screen to what it thought was the native resolution of 1600 x 1000 (?) which my monitor doesn't support. So my hi-tec solution was to boot without extensions, place the Preferences window in the top left of Finder with the Monitors preference icon first, reboot with extensions, and then blindly open the Monitors preferences with my mouse and use tab and up/down to change the resolution. 1920x1080 works just fine!
You will want to install OS9 drivers for your graphics card. Try the Macintosh garden or repo.I have noticed some 'tearing' and graphic glitches in OS 9 at 1080p, do you think it's the limits of the stock graphics card? OS X Tiger works smoothly so I'm surprised it is struggling with OS 9.
This is the keyboard with a power button. Very cool. Very necessary for Cube owners. https://www.ebay.com/itm/Apple-Keyb...317160&hash=item41dfbf7b3c:g:-iIAAOSwwNRa0--rTonight I'm getting this error at boot. As mentioned before my USB keyboard/mouse only works intermittently, not sure if it's the ports or the peripherals. Anybody seen this error before?
