<p> CopyRoms is a very simple program to write out a
copy of the <a href="../../hardware.html#rom">ROM</a>
from a 680x0 Macintosh to an image file.
It should work on a Macintosh 128K through to a
Macintosh IIcx. It should also work on many other 680x0 Macintosh
models, but most haven't been tested. CopyRoms should be
able run without crashing on any Macintosh,
even if it doesn't succeed in saving a ROM image. </p>
<p> To use, just launch the CopyRoms application. It
should write out a file (to the folder containing
the application) and then immediately quit.
On a Macintosh Plus, or Macintosh 512Ke, it should
write out a 128K file called "vMac.ROM".
For the name and size of the file written out on
some other machines see this list of
<a href="https://www.gryphel.com/c/mac68k/index.html">Macintosh 680x0</a>
models. CopyRoms only works on computers with
a ROM whose checksum is included in this list. </p>
<p> If CopyRoms doesn't recognize the ROM, it will
write out a 4 byte file called 'Unknown.ROM',
containing just the checksum from the start of
the ROM. Please send
<a href="https://www.gryphel.com/c/feedback.html">me</a>
this 4 byte file, along with a description of your computer,
so that I can support it in a future version of CopyRoms.
(But only if you are using a 680x0 Macintosh,
not PowerPC or Intel.)
(And don't send me actual ROM image files.) </p>
<p> CopyRoms has no user interface, and so 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 CopyRoms 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 main difficulty in using CopyRoms is transferring
the program to the old Macintosh, and transferring
the acquired ROM image to another machine.
Modern Macintoshes can't use the 800K
floppy disks used by the Mac Plus. The easiest
solution is to use a slightly less old Macintosh
that can use 800k disks, and that has ethernet
or other communication options to talk to
more recent machines. Some other
possibilities are an AppleTalk/Ethernet
converter, an external SCSI drive (though modern
Macs can't use external SCSI drives without 3rd party
hardware), a null modem cable, or connecting
to the internet with a modem.
The Macintosh 128K and 512K are even more difficult,
since they only understand 400k MFS floppies,
and don't have a SCSI port. It is easiest
if you also have a Mac Plus. </p>
<p> The ROM image files that CopyRoms saves are
copyright Apple Computer, and may not be
redistributed. </p>
