Hi,
perhaps what you could do is modify
dev8_smsq_atari_driver_dv3_asm
by putting an rts at label d3r_init.
That way that module will do nothing.
Recompile everything and try to see what happens...

So which is the last(?) module?
This should be smsq_atari_driver_dv3_asm.
Could you check by setting a breakpoint at $12b40 and then follow the code
after the last good break, to see whether it is indeed this module?
You should find the name of the module a few bytes before the address at
which it is called.
I am home again and can do something serious with this. I tried to set
a breakpoint at the rts
after the copy and it seems like the last entry doesn't finish , i.e.
rts is never reached.
Can I (just for test) disable the 9th module?
I know I've asked this before, but isn't there a special code one can use to
cause a breakpoint in your debugger? (i.e. same A line instruction or
something like that).
I don't know. It should be something that causes a exception. I get
exceptions from the hw probing
of VME bus. So perhaps a read from impossible address can do the trick here.
Marcel, I will du a attempt with serial ports if above fails.
