OSD - On-Screen Display¶
Aside from Menus, you can interact with the emulated system through a few On-Screen Display (OSD) elements:
Control Panel¶
This is the "Control Panel" of the system.
To open, press F4 or click the triangle tab that appears near the upper left corner of the display when the mouse is moving.
Inside the Control Panel, you can select:
Display mode¶
NTSC, RGB, and three colors of monochrome
Speed¶
1 MHz, 2.8 MHz, 7.1 MHz, 14.3 MHz, and Ludicrous speed. Ludicrous speed still ties into the normal 1 MHz video system so speaker, Ensoniq, and disk devices keep running (if ludicrously).
Slots¶
Displays what virtual cards are present in slots.
If you are seeing the Control Panel from the System Select screen, it's because you asked to create or edit a System Config, and you will be able to change what is in the slots. Otherwise, it is display-only.
Serial / Parallel¶
Buttons for each serial or parallel port on the machine (IIgs built-in SCC, Super Serial, Parallel, etc.). Click a button to attach None, File, Clipboard, Modem, or a listed host serial port. See Serial & Parallel Connections.
Disk Drives / Storage¶
Drive icons show slot, drive, and the mounted filename (if any).
- Click an empty drive to open a file picker and mount an image.
- Click a mounted floppy to unmount. If the image has buffered writes, you are asked to Save, Discard, or Cancel.
- Drag a disk image onto the window: the Control Panel opens so you can drop the file on the drive you want.
See Storage for formats, write-back, BazFast, and errors.
On Apple IIgs systems, Host Folder… chooses which real-computer directory is shared through Host FST (volume :Host). Not available in the browser build. See Host FST.
Hover controls¶
When the mouse is over the main window and is not captured, a strip of face buttons fades in on the left:
| Button | Action |
|---|---|
| RESET | Same as Machine → Reset (Ctrl-Reset) |
| Capture | Capture the mouse for guest pointer software |
| Debug | Open the debugger window (same as F10) |
| Speed | Shows the current throttle (1.0, 2.8, 7.1, 14.3, or an infinity glyph for Ludicrous). Click to open a picker. |
| Display | Opens a picker for Composite / RGB / mono. The button accent follows the current monitor. |
The strip hides automatically when Capture Mouse is on, so you do not click buttons while using mouse-aware software. There is no Display → Hover Enable menu; the strip appears whenever hover is possible.
The triangle Control Panel tab (upper left) is separate from this strip.
Disk Drive Status¶
When the Control Panel is not open, if disk drives are active, they will be displayed at the bottom of the screen, indicating slot, drive, track number, and disk image filename if an image is present.
You can hide this strip with Display → HUD → Drives. The stats overlay (if enabled) is toggled with Display → HUD → Stats. See Menus and Displays.
