I just recently purchased a Mac IIsi and can't get the interrupt key combination on the keyboard to work. Supposedly command-powerkey should do it. Do I need a special version of Macsbug for this to work (is there a new one?) ? If so where can I get it? -Sherman. P.S. the reset key combination works fine (command-control-powerkey)

This works on all the IIsi's I've seen (both of them!). If this is intentional design by Apple, though, I don't follow the reasoning for it; it certainly seems to shoot down any hopes of debugging anything that happens quickly, unless you can predict at least one second in advance what's going to happen. Does Apple honestly think that someone's going to hold down Command and press the Power key accidentally?

If the 1 second interval is done in software, it should be possible to change. Does anyone actually know how it's implemented? -- Philip Machanick philip@pescadero.stanford.edu

The Macintosh LC and Macintosh IIsi do not have a programmer's switch. Here are the key combinations for the Reset and Non-maskable interrupt (NMI) functions: - Control-Command-Power generates a reset. - Command-Power generates an NMI. These key combinations are similar to those used in the Apple IIGS. Note: MacsBug 6.2b1 or later needs to be installed for the non-maskable interrupt to happen when the Command and Power keys are pressed.

I've been posting this question everywhere I could, in case no one noticed 8^) I got one reply from another Usenet reader, twl@cs.brown.edu (Ted "Theodore" W. Leung) who said he tried it in a store where it worked and the Macsbug was 6.2b1. Well, I dug up a copy here in the silicon valley of 6.2b1, and he is right! When Macsbug 6.2b1 is loaded the command-poweron key breaks instantly to the debugger. Why couldn't readers of this newsgroup from Apple answer the question? Are they ALL off somewhere else right now? Maybe, they've been silent lately. Now all you IIsi owners have to chase down a copy of this version which isn't (I know) easy to find. All's well that ends well (for me; I wish you people not in this valley good luck in finding a copy of 6.2b1, it was hard enough here, and I *thought* I had good contacts!). jim -- __ __ / o / Jim Budler jimb@silvlis.com | Proud / / /\/\ /__ Silvar-Lisco, Inc. +1.408.991.6115 | MacIIsi /__/ / / / /__/ 703 E.

I apologize to these Apple employees for misdirecting my anger at Apple for failing to provide the information making a specified function of my MacIIsi work. For those who missed the thread, the interrupt on the MacIIsi only works when you have an unreleased version of Macsbug, 6.2b1 or newer. For those unfamiliar with Apple versioning, 6.2a? and 6.2d? are not newer, and they don't enable the command-poweron for the MacIIsi. The released Macsbug 6.1 also does not. Scott Winder <winders@aux.support.apple.com> *did* provide the necessary information.

I am using Macsbug 6.2b5 with no problems. The debugger does come up as white text on black background, however, which seems a bit odd. Steve Strange
