Hello!
I want to speed up the interrupt (original #38).
So I use the #FD9A for jumping to my own routine (which will
pop the return-adress from the stack), checking the Vertcal-
Blank flag and only the absoult necessary things.
Everything is fine, BUT - there are still two things which
I would like to remove...
the call to the old #FD9A, and the call to #FD9F.
#FD9A: called on every interrupt which occurs,
normally not used by the system, only some special software.
- there shouldn't be problems if I won't call this old entry
#FD9F: called 50/60 times per second,
a restard-command to stop the diskdrive.
- before disabling this call, I will call it 256 times after
a diskoperation to stop the drive.
What is your opinion? Will I be in troubles by removing this two calls?
thanx in advance for your help
greets
wolfgang
