- #5: Check on Mouse Firmware Card
-
- Revised by: Matt Deatherage November 1988
- Revised by: Rilla Reynolds November 1985
-
- This Technical Note formerly described a protocol which allowed applications
- to check a device which matched the mouse firmware identification for support
- of interrupts.
- _____________________________________________________________________________
-
- The convention formerly described by this Note has been removed since it
- conflicted with the Pascal 1.1 Firmware Protocol. The conflict could cause
- Pascal to believe that optional firmware routines were present, when the card
- being checked was simply stating that it supported interrupts.
-
- Apple recommends that any mouse-type device which matches the mouse ID bytes
- should support interrupts exactly as the Apple mouse firmware does.
- Applications which believe they have found an Apple mouse have a reasonable
- right to expect that the device they actually have found will behave as an
- Apple mouse.
