Start up in configuration mode
The IMSAI 8080 replica has a special start-up mode for configuring ROMs and other settings (e.g. selecting between Z80 or 8080). To enter this mode:
- Connect the power supply, but turn the PWR switch to OFF.
- Hold the EXAMINE toggle up, and keep holding.
- Turn the PWR switch to ON, still holding EXAMINE.
- Take a breath, and then release the EXAMINE button
The LEDs should be flashing.
CRT Full-screen Mode
The Desktop UI CRT view has a full-screen mode. To exit this mode, press ALT and ESCAPE.
On some systems, this key combination is intercepted by the OS and so nothing will happen. You'll need to reload the Desktop UI in this case.
Ctrl-C when changing disks
