Please do not post requests like this to the PIC mailing list.  The members
of this list are   responsible, hard working people and have no interest in
aiding you or anyone else to steal other peoples work.  OTOH if this is for
your own use, no-one can (easily) stop you from reverse engineering the
function of the device and coming up with your own solution.  It just take a
bit more skill and a bit more time, and the results are always far more
satisfying.

Regards

Mike Rigby-Jones

You will need a 22.5 volt supply capable of supplying a minimum of 1.5
amps, hook up a 10,000 uf capacitor in parallel to this supply and apply
0 volts to pin 14 and 22.5 volts to pin 5. Turn power on for 10 seconds
and the copy protection will be destroyed !

Graham Daniel.

Steam engines may be out of fashion, but when you consider that an
internal combustion engine would require recovery of waste heat by
transfer just before top dead centre then fashion becomes rather
redundant, USE STRATIFIED HEAT EXCHANGERS ! and external combustion.

I believe that Daniel's intention was not to copy other people's job,
but it is a good point to talk about, since the Internet and BBS's
around offer all kinds of services, reputation, members, quality,
exposure, seriousness and other adjectives.  Sometimes a person used to
frequent a heavy piracy place or hacking group (nobody's land) just hit
other place's door asking the same things he is used to get at his usual
places, it looks like a drunk guy asking beer in a church.  Initially we
could condemn, but later on we understand that sometimes we do things
like that in different ways and situations.  Daniel's post shows that he
is somehow newbie in the list, based on the html post and the address
card attached, things we do not recommend, to keep the bandwidth low.  I
am sure that when the hungover passes, the drunk would start o pray in
that church.  :)

Does this work for another PICs (16x7x, 16x8x - taking care about pins)

The other PICS require immersion in a solution of 1 part - 30% HCL,
1 part - chewing tobacco, and 1 part - SPAM.  Then apply 120VAC, be
careful not to kill yourself!  If you do this, I am not responsible
for what happens!!!

I feel it important to note that Graham was kidding too and so was
Neven?.....  don't try the above!!

I must also note that indeed there are times where removal of copy
protection may be warranted.  Perhaps due your dog eating the source
diskette, poor revision control, an oops! on a JW part, or perhaps
a contractor who is a real jerk and holding you for ransom.

Whatever the case, if it is indeed warranted, it is typically due to
stupidity, and I'd take it as a learning experience and move on!

BTW... If anyone is in the above 'warranted' situation, I would be
happy to help 're-develop'.  I've LEARNED from the above, and am
not so stupid now.

To add something FRESH...

Has anyone experimented with self destruct mechanisms, for people
attempting to reverse engineer your product?

It amazes me.  Every time.

The first thing any corporation that wants to "enter the market" does is
to reverse engineer the competition.  All the semiconductor manufacturers
have equipment to sniff what's going on inside of packaged devices, hell,
one of my professors made his living for a while at TI doing this.

What blows me away is the strange "morality" everyone has:  it's ok for
Megacorp Unlimited to do "research" but as soon as an individual does it
it's theft.

Hacking is hacking, corporate or not.  It has been, and always will be,
the prime mover of technology.

Keith:
If I copy your code it is plagiarism or theft, but if I copy from
many sources then it becomes research.

Hi to all ,

Speaking about reverse engineering I do not see any problem
breaking the code "if you can"  if you can't you may find
some one that can . learning more about architecture
is very good idea code protection is part of architecture so how
come it suddenly became {OT}. I personally found that many hackers
know about MCU lot more then any high end engineer and most
of them  write their own code. Knowing more about code protection
bit it doesn't mean preparing to still some one else's code.

 (To use something quite relevant to one of my projects, here): What
about when the design someone else makes is inefficient, ridiculously
limited, and uses far more resources than your design, requires a
software driver, and is otherwise obnoxious and quite overpriced?
(We've seen Compaq clone the IBM PC, of course, for another example, and
there were some barriers they had to use internally to do this. <G>)

 I'm not reverse engineering that machine (Don't have one.  Bought one
for a friend, but had it shipped directly to him.)  It's pretty darned
obvious what this machine does, and it's pretty obvious that for about
1/4 its price - maybe less, I can build a machine that does the same
job, doesn't steal a serial port (rare on the target machine), doesn't
need any software driver (so it'll work under ANY OS), and should
otherwise be more flexible and easier to cope with.

 I wouldn't crack their code, that would be theft - but I feel free to
make my product able to use a similar (perhaps the same) macro setup,
though with 20 times more macros as I put some real memory in there <G>,
and in general easier to use, fairly different, and probably a really
effective competitor to the other widget.  (And it'll be GPL'ed.)  They
may not be very happy about it - but if they'd paid attention to what
the market was asking for, I wouldn't be interested in making this, I'd
just buy one & be happy I didn't have to spend any of my time <G>

 IMHO, There are places where copy protection is irrelevant, places
where it's a very good idea, and places where it seriously hurts and
annoys the user (Such as printer port anti-theft widgets.)  It stops the
honest investigative learner just as often - and usually for far less
time - than it stops the criminal hacker.  Easy enough to put in "Easter
Eggs" to prove if someone used your code & thus violated your copyright,
as one alternative...

It works especially well in cases where a high volume product can be
built in China at 1/10'th the price of the authorised version.

Along with that, the (fried) PIC too for breakfast ;-)
