[comp.sys.atari.st.tech] parasite interrupt

arditi@taloa.unice.fr (Just call me "Master) (04/26/91)

I have e strange problem that I will try to explain...

I did a program wich starting address is $8 so it overlays all interrupt
vectors. Of course I set SR to $2700 ( No interrupts should happen).
On Atari STE and all STF except the serie which was sold just before STF
had a double sided drive, my code works well. But with this serie it bugs.
I discovered that on that serie, a parasite interrupt ( I don't remember
its number) happens.

So I would know if someone knows what starts this interrupt on ST and why
it does not work same on all different mother cards.
I think a good technician, a member of Atari Corp. could answer me.


Thank you.

PS.: Excuse me, I'm French so my English is...you know !
