level 7 interrupt on A600

xc8 · 26 October 2008, 14:25

hi,

Are there any schematics to do this?

In fact I want to trigger the htrmon under the WHDLoad (on an A600).
I supposed i need an NMI button to enter to Hrtmon, as the "/" or right mouse button does not work to enter to hrtmon (when a game is loaded with the WHDLOAD (using the D parameter))

basically you can use http://whdload.de/docs/en/opt.html#FreezeKey option to enter the freezer while in whdload, but it will not work on most installs on a 68000 which you probably have

check out the docs of hrtmon which should include schematics for a nmi key on the a1200, on the a600 it should be nearly the same (you need to put all three int lines on ground)

on the 68000 the installed program may also overwrite the nmi vector which will permit entering hrtmon
