The combination is Command-Control-Power, I think. And there's an historical reason for it. In the Apple II, the Control-Reset combination really stopped the running program and dropped you to the BASIC or monitor command prompt without rebooting, so you could recover the memory's contents. The "Open Apple"-Control-Reset combination forced a "warm boot": the computer rebooted just as if you powered it off an on. The "Open Apple" and "Closed Apple" keys were two modifier keys located at the sides of the space bar and used to issue keyboard commands in the same way as the Mac's Command key. Later, when the IIgs incorporated the Command key, it wasn't put in the keyboard as a separate key, but was combined with the Open Apple key. That's why ADB keyboards have an Apple logo in the Command key. > so it > is a separate line as you say but can it still be read by a DA for example? The key is readable by software, it's obvious. But maybe it's intercepted by the System or the ROM (in wich case you wouldn't be able to read it from any kind of software, were it a control panel, a DA, an extension or whatever). The answer should be in Inside Macintosh, but I do not own a copy... :-\ > As your other post indicated later OS's support it on the same hardware so > it is only a software or OS issue as far as I can see. In your case, it seems as it's only an OS issue. It works for me with System 7.6.3, and Dylan has said that it also works with 7.5.5. Maybe copying one extension from OS 7.5 into your 7.1 will do the trick. I couldn't tell what extensions to try...

For example, in the //e and //c (which didn't have Option key), the self test was invoked pressing Open Apple-Closed Apple-Control-Reset (a really difficult combination!), or pressing both Open Apple and Closed Apple while powering the computer on. And the II and II+ didn't have a built-in self test. About the "Reset as break key" thing, it is as it was designed in the original II (it didn't reboot the machine but allowed you to debug the program in memory). In the II and the early II+ (the units made before 1980, I think), Reset worked by itself, without requiring you to press Control. Because the Reset key was located on the very same place where most modern computers have the Delete key (right above the Return key), it was a very frequent problem to press Reset without wanting to and lossing what you were doing or typing. In later revisions that was fixed by linking Reset to Control by a hardware switch which allowed you to "configure" that feature. The later Open Apple-Control-Reset combination allowed //e and //c users to easily boot a new disk without having to drop to the command prompt and keying a cryptic reboot command (ussually "PR#6" or "6<control-P>"... the easiest things to remember!).
