<p> EgretRom is a utility to write out to an image file a
|
|
copy of the ROM of the Egret microcontroller used to
|
|
manage power in some Macintosh models. It was made at the request of
|
|
<a href="http://rbelmont.mameworld.info/">Arbee</a>
|
|
(AKA <a href="http://retroblast.arcadecontrols.com/articles/belmont.html">R. Belmont</a>),
|
|
to assist the <a href="http://www.mess.org/">MESS</a> emulator project. </p>
|
|
|
|
<p> It was made from Arbee's specification, and he reports that the
|
|
"second version works fine and has been used to dump
|
|
Egret/Cuda/Caboose ROMs on everything from '030s to G3s".
|
|
(I don't have the hardware to test it myself.) </p>
|
|
|
|
<p> The MESS
|
|
"<a href="http://mess.redump.net/mess:driver_info:mac_technical_notes#what_chips_are_in_what_macs">Mac Technical Notes</a>"
|
|
document some Macintosh models that contain Egret and Cuda. </p>
|
|
|
|
<p> To use, just launch the EgretRom application. It
|
|
should write out a file named "Egret.ROM" (to the folder containing
|
|
the application) and then immediately quit. </p>
|
|
|
|
<p> On a machine without an Egret microcontroller, EgretRom
|
|
may or may not detect that, and give an error message.
|
|
(If it doesn't, a crash is likely.) </p>
|
|
|
|
<p> EgretRom 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 EgretRom set to be the startup
|
|
application (in System 6 or earlier, not System 7),
|
|
and replacing the finder with the
|
|
"<a href="../autoquit/index.html">AutoQuit</a>"
|
|
application. Make sure there is
|
|
enough free disk space for the ROM image file. </p>
|
|
|
|
<p> The ROM image files that EgretRom saves are
|
|
copyright Apple Computer, and may not be
|
|
redistributed. </p>
