ROM 00 to ROM 01 upgrade

["Steve Q" <sqnospam@superbio.notrash>]

Greetings, all...

I've got a ROM 00 "Woz Limited Edition" boat anchor that I picked up cheaply
some time ago.  I got on the horn with AllTech a few days ago and asked
about the ROM 01 upgrade that they've been known to carry, and I was lucky
enough to hear "We have one left."  OK, it's on its way to me, and at least
I'll be able to boot GS/OS on this thing.

My question is this:

I'm not much of an electronics person, but a good friend -is.-  Let's say
that I'd like to copy these ROM 01 upgrade chips, so that if I'm ever in
this predicament again, I can simply roll my own (and for personal use...I'm
certainly not looking to pee on anybody's lawyers or anything like that).
Is this doable?  If so, what kind of chips would I need to get?  Any
suggestions, specs, etc, would be greatly appreciated, and thanks in
advance.   And yes, my wife has reminded me that I pour more money into
these systems than what they're worth, but dammit, it's not the kill but the
thrill of the chase. :-)

PS:  Is there any way to identify a ROM 00 versus a ROM 01 versus a ROM 03
simply by looking at the case (assuming motherboards haven't been
transplanted)?  The classic method is to boot the system, but once in
awhile, I find systems that are sold by organizations that won't let you
fire them up inside the place (even though they allow returns).  I'd guess
that the answer is "No," other than maybe looking for "1989" on the ROM 03,
but in case someone knows a trick I don't know, I'd love to hear it.  Thanks
again.
