Doesn't sound like IBM. As my brother once said, "if you want to know
where your company's profits are going, buy an IBM computer." ;-)
He'd know when and where - in the monthly lease payment.

They told me that this originates at IBM. I had attributed it to some
Siemens guy.

Ofr prototypes, you made the mistake - own it. ;-) Production frowns
on such things though. BTDT.

That'S me for the five prototypes. As far as I know my customer I expect him
with change requests after seeing the prototypes. So he will pay for fix.
There is an old saying attributed to IBM sales guys: The customer will pay
for it, he just may not know when and how.

Ah, the oops register bit :-)

So far, yes, knocking on wood. I am surprised that there isn't an oops
chip for this. Like a crosspoint gender changer SMT thingie that you can
buy in a through and a cross version. After all, they used to make oops
transistors in the early days of SMT when people messed up the SOT23
footprint. Not sure if they still make those.

Just have three or four people each check it five times.

I still have a Smart Cable that does that. For my own stuff, I used to
rely heavily on Jan Axelson's "Serial Port Complete".

Without thinking about it, the odds are 50% for right and 50% for wrong.
Thinking about it moves this more to the wrong side.
