PMURom is a utility to write out to an image file a copy of the ROM of the Power Management Unit (PMU) used in some Macintosh models. It may work on the Macintosh Portable, and PowerBooks 100, 140, 170, 160, and 180. It was made at the request of Arbee (AKA R. Belmont), to assist the MESS emulator project.
It was made from Arbee's specification, but it is not yet tested. (I don't have the hardware to test it myself. My PowerBook 100 is dead.)
To use, just launch the PMURom application. It should write out a file named "PMU.ROM" (to the folder containing the application) and then immediately quit.
On a machine without the right kind of PMU, PMURom may or may not detect that, and give an error message. (If it doesn't, a crash is likely.)
PMURom can be used even on a machine without a working keyboard, mouse, and/or screen. This can be done by preparing a floppy disk with PMURom set to be the startup application (in System 6 or earlier, not System 7), and replacing the finder with the "AutoQuit" application. Make sure there is enough free disk space for the ROM image file.
The ROM image files that PMURom saves are copyright Apple Computer, and may not be redistributed.
