Lisa Hardware Interface 9.1 source

may take a day for the mirrors to catch up

hopefully, attachments work here. I've included a python program that can extract 5 1/4 and Twiggy monitor files

Lisa Hardware Interface Software
________________________________________________________________________________


The software below provides an interface for accessing and controlling several parts
of the Lisa hardware.  This interface is intended for use by several operating systems,
including the Lisa OS, the Monitor OS and Smalltalk.  The following hardware/software
capabilities are currently addressed:  the mouse, the cursor, primary and alternate
displays, the contrast control, inactive fading and power-off, the speaker, both
undecoded and decoded keyboard access, the NMI key, the millisecond timer and alarms,
the microsecond timer and the hardware clock/calendar.

Both Pascal and assembly language interfaces are supported.  Three distinct ways of
accessing the hardware interface routines exist.

     1)  From Pascal, compile using unit HWINT, link with HWINTL.OBJ.  Pascal
         register and calling conventions are observed.
     2)  From assembly language, JSR to the Pascal routines defined in HWINT.
         Link with HWINTL.OBJ.  Pascal register and calling conventions apply.
     3)  From assembly language, trap to the routines with parameters and
         results passed in registers.  All (non-parameter) registers are preserved.

All of the capabilities defined below are available in the assembly language
interface.  Most of the capabilities are also available from Pascal.  In the Lisa
Office System, most of the the routines will be called from the OS, LisaGraf and the
Event Manager, not directly from applications.  I repeat, most of the the routines
are only to be called from the OS, LisaGraf and the Event Manager, and not directly
from applications!
