[comp.sys.mac.programmer] Disable mouse interrupt?

cpyang@ccnysci.UUCP (Chao Ping Yang) (11/04/88)

We are trying to interface a Mac II to a PI instrument and the
timing of the PI is such that we would like the Mac II to go
even faster. One thing we wonder whether possible is to disable
the mouse or any other interrupts so that the MacII is dedicated
to the data transfer when required.

Your help will be greatly appreciated.

Boy, I don't know if you should be allowed to do such violence to that
nice Mac II that so many of us would love to have.

Disable the Mouse?  The only time the mouse is going to steal any CPU
is when the user moves it, which might mean the user is trying to tell
you something.  One of the prime user interface commandments is that
thou shalt be responsive to the user. 

Are you sure this is a job for a Mac?  Wanna trade it for a nice
MS-DOS machine where interrupts are free game?  I'll BUY a _FAST_
80386 computer just for the trade.

(Seriously, I doubt you are losing any measurable CPU time to a quiet
machine where no one is playing video games under MultiFinder.)
