The last board that was laid out by software had an INTERUPT line running to the interupt pin on the microprocessor

 If I may interrupt for a moment.
 A chip and a PCB (printed circuit board) are laid out.  It's possible
that someone might lay out a software flow chart, but I've never seen
the term used in that manner.
 Reminder:  The surest indications that someone has no experience with
the technology is the tendency to butcher the spelling, use the wrong
industry terms and are unfamiliar with the relevant jargon and
acronyms.
 

There is not a microprocessor that has ever been designed with an
"interupt" signal.

 The Intel 8080 two hardware interrupt lines.  NMI was a non-maskable
interrupt and INTR was a maskable interrupt which has a lower
priority.

 The later 8085 had 5 hardware interrupt pins.

You missed the point. I was criticizing his spelling. All microprocessors have "interrupt" lines. None have "interupt" lines. If one is attempting to write code for a microprocessor and starts writing "interupt", they going to have a lot of problems.

 

Computer Science 101 - consistency in terms. But according you you,
spelling shouldn't matter.

 I wished it were so.  I've seen far to many terms be re-used and
technical terms replaced by marketing jargon to allegedly simplify
things.  Intentionally wrong spelling to avoid trademark infringement
really irritates me.  Bad spelling would probably disappear if there
was some means of enforcing correct spelling.  The good news is that
software is rather sensitive to incorrect spelling of instructions.
The bad news is that most code generators, compilers and AI
auto-plagiarizers now include a built in spelling checker. Eventually,
the documentation will have perfect spelling once AI takes of the tech
writers job.  Of course, it will still be unintelligible, make little
sense and resistant to decryption.  I had to deal with such a manual
when installing a CNC controller where the documentation was probably
a Google translation from Chinese to English.
 

And this was the latest and greatest board layout programs in 2008.

 Tom.  What was the name and version of this latest and greatest PCB
layout program of 2008?
 Diversion:  This is how "real men" did PCB layout on mylar with Bishop
pads and tape for the traces and red rubylith for the ground pours

Oops... What is a White home sewing caching doing in my web pile? I'll

You are so full of shit about the Techtronix wire fault detector

Then prove it. Show me a link anywhere that shows how to use PWM to test
cables.

 For me, Tom's problem is not PWM but rather that Tektronix doesn't
make a "wire fault detector" but instead makes "cable testers". Plenty
to choose from:

Again, not knowing the correct terms is a good indication of Tom's
lack of experience with the technology and devices.
