ahh i see.. if youre in deep shit you need to do error handling... makes sense 😆..
i'll see if i can rephrase the syscall thing

@tecneeq
one could try to see if the keymap memory region is properly populated when pressing esc + l + f + w. This can be done by entering the debugger and entering "DM 174 " (with space at the end) and then press "esc + l + f + w + enter".. this is bit a hacky method, but it works on my IIci..
DM 174 dumps the keymap memory location and if you put a space after it, everything you enter then is ignored by the debugger.. thus "esc + l + f + w + enter" does not interfere with any debugger command or so...

but I have the feeling that the keymap works fine and the error lies somewhere else, i guess it wouldn't crash if the keymap was wrong

maybe you could also hit the debugger switch when the system hangs and then see where the program counter points to by entering "PC" or dumping all registers with "TD"

Ok, so just tried it with my 650. Keystroke doesn't work. But, the debugger command works fine...with one caveat. If you click on the image after it pops up, the machine locks up solid. Won't even respond to the programmer's switch buttons. Nor does the command-control-power keystroke. So, have to manually reach behind and hit the power switch to shut it down.

So, just with regards to it not working for everyone. I think I remember that there are two ROM versions fitted to the 650.

To be clear, I have a *Centris* 650, that shipped at 25MHz, so it is an earlier 650. Might everyone else have the updated ROM?

Mine is also a stock C650 that shipped with a 25MHz '040 chip. I did upgrade it with a 33MHz chip, but the computer still reports itself as being stock, since I haven't changed the resistors on the underside.
