When I first got my Mac+ a month ago, I was usually able to use the Interrupt switch to go into the mini debugger, although I didn't know any useful commands at the time. Now I have read some useful commands, but the switch is no longer working properly. When I push the Interrupt switch the machine just freezes, and the mini debugger window is not displayed. Does anyone else have this trouble? -- Barry Margolin ARPA: barmar@MIT-Multics UUCP: ..!genrad!mit-eddie!barmar

The 16 page document (that, of course, was not backed to to floppy) was due today. *ARGH* The machine would not boot--only a blank black screen. Fortunately, I checked the interrupt switch which was stuck in its depressed position. Evidently, the "programmer's switch" does not fit the new case properly and sticks. One would think that if Apple had not redesigned this feature, they at least would have made their existing implementation usable. -- -------------------- Dave Thompson uucp: {ihnp4 | hplabs | psivax}!csun!dlt CSUN Computer Center Northridge, CA 91330

When my interrupt switch started sticking, I sought and found an excellent alternative: a toothpick, and a scribed line on the Mac's case to mark the boundary between "interrupt" and "reset". It's cheap, it's reliable, and you can chew on it when things are going wrong...

We successfully "fixed" a programmer's switch for the Mac+ by trimming a *very* tiny bit off the end with an exacto knife. *BIG DISCLAIMER* -- I will take *NO* responsibility for your ruining your own programmer's switch. But it worked for us... :-) Bart Massey ..tektronix!reed!bart
