Enterring a blank command continues the disassembly or stepping for one instruction. Erasing the prompt saves one line in the console so the disassembly doesn't appear double spaced. I don't know if the terminal control sequence works in Windows.
Bit 5 of the channel status register of the SCSI0 DMA channel
reflects the DREQ signal from Curio.
The old SCSI API still used in some Macintosh applications
- most notably HD SC Setup and Drive Setup - relies on this API
and that signal to be implemented.
All AppleJack controllers start in mouse emulation mode, behaving exactly like
ADB mice. Only upon receiving a Listen command on register 3 with handler ID
0x46 does the AppleJack switch protocols, albeit such a change consisting merely
of expanding register 0's buffer size to 4 bytes. In this state, the first 2
bytes remain defined as they are for an ADB mouse; the additional 16 bits carry
the respective states of each of the AppleJack controller's remaining 11 buttons
out of a possible supported 16.
For backward compatibility, honor both mouse clicks and shoulder button presses
on the host when considering the state of the emulated trigger buttons.
Add new GamepadButton enum with bits corresponding to AppleJack button bits.
Both the AppleJack controller and the SDL GameController coincidentally define
one d-pad, two shoulder buttons, four face buttons, and three system buttons.
This makes mapping modern game controllers to the AppleJack straightforward.
AdbMouse and AdbKeyboard are subdevices of the CUDA device alongside AdbBus.
This doesn't make sense because conceptually, ADB devices hang off of the ADB
bus, not CUDA itself. An ADB bus can exist without a CUDA present, for example
Egret on older 68K Macs and the PMU on newer Power Macs. Therefore, make the ADB
device list a subhierarchy of AdbBus instead. Add a new "adb_devices" property
belonging to AdbBus that can allow users to specify ADB devices on the command
line at machine creation time, independent of the emulated bus's host. Make this
property default to "Mouse,Keyboard" to preserve existing behavior.
Add New World ROM Layout notes.
Add New World Firmware version notes.
Add punctation.
Move mention of OF main fcode image from the Open Firmware kernel description section to the boot process section.
Shutdown will enter the debugger or quit depending on the execution mode.
Quit is different from shutdown since it is triggered outside the guest by using the host Quit menu item.
