On my Apple IIGS, the Control-Open Apple-Reset (exactly the same thing as Contol-Command-Power, the GS was the first to use the ADB) will make the ADB microcontroller pull the /RESET line low. Since this is entirely in hardware, there is no way a program can affect the ability to reboot. I'm sure this would more or less apply to the si also. Also, the reset always works, but the interrupt doesn't always work right. However, if you have MacsBug 6.2(?) or later, the interrupt works fine. Side note: sometimes a reset switch on the cpu box doesn't work all the time... Pitfall on the Commodore 128 would not allow you to reset... it would start itself back up.

According to Apple's notes for developers, in addition to the 68030 in the si, there is a processor in the keyboard, and a third processor, a 6800, in the CPU box, who's dole job is to service the keyboard. If the 6800 sees a long <Command><Power>, it sends an NMI to the 68030. Unlike on an IBM PC, on a 68030 you can't mask an non-maskable interrupt. (No smiley, due to stupid hardware design at intel, you really can mask a non-maskable-interrupt on an intel processor.) -- -- David Phillip Oster - At least the government doesn't make death worse. -- oster@well.sf.ca.us = {backbone}!well!oster

Yes, this is very intuitive for Apple because it means one less external switch to worry about. Thus making the machine less expensive. Actually, this has been available for the Mac II for a long time. It is called Programmer's key (by Paul Mercer) and I believe it is the prefered method amoung most programmers to reset their machines. The latest version of Programmer's Key allows you to selectively switch which debugger to break into, TMON or MacsBug. This actually involves many more combinations of keys depending on the debugger you want to be in. Quite a nice hack I must say. - Paul -- ------------------------------------------------------------------------------- | Paul C.

Does that mean that I cannot do a NMI from my IIsi with a Datadesk Switchboard? I have noticed several times when the mac will crash and I cannot reboot. I have to use the power switch. The silly switch is configured so I have to turn off power altogether and turn it back on. I cannot "reset". This usually happens with new programs or inits I get. I just need to reboot and deactivate them. ------------------------------------------------------------------------- J. D.
