Is it legal to copy the Mac ROM data onto a diskette?  If so, perhaps a
'leach' technique could be used by a mac-compatible machine.

First, the buyer of the mac-compatible could be provided with a program
which would save the ROM routines (all 64K) on the provided disk.  This would
be a one-time operation for the customer.

Second, a mac-emulator program could then be run on the mac-compatible which
would load the ROM routines into a 'special' section of RAM that could sub-
sequently be write-protected (virtual ROM, if you will).  One might think of
the emulator disk as a 'MacWorks' for the proposed mac-compatible machine.

Oh, yes, the Macintosh is able to access its ROM faster than its RAM.  If
equal (or superior) performance is desired, then the clock rate of the mac-
compatible could be boosted (and the 68000-10 could be used, if necessary).

Once again, my original question:  Is it legal to copy the Mac ROM data onto
a diskette?  (The data would *not* be packaged with the machine; the customer
could merely find a friend's mac to get the data from)

Also, has anyone thought about designing a replacement-board for the Mac which
would upgrade the data bus lines to 32-bits (for the 68020, of course)?

You must be confusing proprietary information with trade secrets. 
Proprietary means property.  That's all it means.  

Copyrighted means the right to copy an article is governed by the
laws of the United States.

You will very often find copyrighted proprietary information.

Try the source code for Unix.

Not so!  Unix source code hasn't carried copyright notices for a long
time.  Why?  Because copyright implies *publication*, and is -- more or
less, roughly speaking -- incompatible with trade-secret protection,
which is how Unix innards are protected.

proprietary information and copyright are mutually exclusive.

An Apple employee who worked on the Mac project told us that the Mac ROM
actually has a theft protection device built in.  We couldn't get any
details, but the idea was that if you copy the Mac ROM, Apple will be able
to take your machine into court and make the ROM do something dramatic and
unexpected to demonstrate that they understand it much better than you do.
Maybe it prints out "Help! I'm Stolen!" or something like that.

All you have done is changed the illegal act from the manufacturer
of the clone to the individual purchasers, perhaps making it more
difficult for apple to prosecute but NOT more legal.
