-
- ; Created: 07/23/87 PM - 1.0D1 first cut using VBL task to call Debugger
- ; Modified: 07/24/87 PM - 1.0D4 changed to use AutoInt1 instead of VBL's (yay!)
- ; 07/26/87 PM - 1.0D5 changed key combinations (works better with TMON)
- ; 07/26/87 PM - 1.0D6 added FlashMenuBar to ShutDown
- ; 08/04/87 PM - 1.0B1 added BufPtr -> sp for _ShutDowns in TMON; its stack
- ; too small, changed key combinations again (for ICOM)
- ; 12/29/87 PM - 1.1B1 removed BufPtr -> sp (see above)
- ; added support for classic keyboards, changed key
- ; sequences again, revved for ShowINIT31
- ; 01/31/88 PM - 1.1B2 added oldAutoInt7 for dual-debugger hack
- ; fixed option key bug on Classic keyboards
- ; 03/04/88 PM - 1.1B3 ADB sense code changed to use HWCfgFlags since
- ; SysEnvirons doesn't tell all about ISO, etc.
- ; 05/06/99 PM - 1.1B4 changed option-break to swap entire exception vector
- ; for better dual-debugging
- ; 05/09/88 PM - 1.1B5 changed option-break to always go to boot debugger
- ; 05/27/88 PM - 1.1B6 added _Debugger swapping to option-break
-
- Tester Notes
- ------------
- *** The keyboard combinations have changed again, see the chart below ***
- 1.1B1 now supports the classic keyboards. Try it and see what I mean.
- The 'hot' key is also configurable. Let me know if you care.
-
- There is also a very sick hack in this version which allows the use of
- 2 debuggers. An example: if you rename Programmer's Key such that it
- loads before TMON, then pressing option-power will invoke MacsBug or
- the ROM minidebugger while all the other keyboard combos will still get
- you into TMON. This feature is still under construction and has many
- pitfalls. For instance, what happens when you use breakpoints with
- both MacsBug and TMON installed? Save all your files and try it.
-
- *** addendum to above ***
- The entire exception vector table is now switched out with option-break.
- This means MacsBug & TMON can almost coexist. Try it!
-
- General Info
- ------------
- Programmer's Key is a small INIT that allows the use of the 'power-on' key of an
- Apple Desktop Bus keyboard as a substitute for the Programmer's Switch.
- To install Programmer's Key, simply drag it into your System Folder and reboot.
- You may then use the following key combinations:
-
- ; Trap Signal = Power-Command-Option (applies to TMON only, else the same as Interrupt)
- ; Interrupt = Power-Command (for like real Programmer's Switch)
- ; BootDebugger = Power-Option (allows use of MacsBug)
- ; Reset = Power-Command-[Control or Tab] (like real Programmer's Switch)
- ; Restart = Power-Command-Shift (uses ShutDown Manager)
- ; ShutDown = Power-Command-Shift-Option (uses ShutDown Manager)
-
- To temporarily disable Programmer's Key at boot time, hold down the mouse button
- or the shift key. To permanently disable it, drag it out of the System
- Folder.
-
- Programmer's Key will work with any debugger, including the microdebugger in the
- 128K+ ROMs. The use of the ROM debugger is discouraged since it does not
- have any builtin mechanisms to guard against potential problems such as
- interrupting a VBL task or interrupting itself. However, Programmer's Key is no
- more dangerous than the real programmer's switch.
-
- Note:
- If you experience any weird behavior with the ROM debugger, please let
- me know. I have tested Programmer's Key with the ROM debugger and have had
- intermitant problems after using _ExitToShell. I'm not certain Programmer's Key
- is causing the problem.
-
- Programmer's Key will not Restart or ShutDown if the file system is busy, so
- if it doesn't seem to be responding, keep on holding the keys down.
-
- Note:
- There is a problem with the ShutDown key combo; if _ShutDown is
- called while the 'power-on' key is down (thereby causing an
- immediate reboot), the keyboard will not function properly.
- If this happens, you need to ShutDown, wait a few seconds and
- power back up. This appears to be hardware problem.
- I haved added a menubar flash as well as a short pause to the
- ShutDown key combination so there is a chance to release
- the power key.
-
- The code to display the icon at boot time is called ShowINIT and is in the
- public domain and available from me directly. If you'd like to use it in your
- INIT, please drop me a note.
