'Picmaster reliability'

We keep breaking Picmaster pods here at work, and can't figure out why.
So far we have had about 5 replaced, all because the emulation memory
failed at some point.  The latest one I used for over 7 months, almost
every day, with no problems.  I hooked it up again after three weeks of
disuse, and it is no longer operating correctly.

We don't use any power supplies over 5V, so shocking the probes seems
unlikely.  Most of our designs are actually 3/3.3V units anyway.

If anyone has any ideas, or has had similar problems, please mail me.

Static Electricity - isn't it summer in USA ?

Capacitive charge differences on equipment when connected - standard
hot plug problem ?

Static - less ozone means more UV means more static ;-)

Seriously, do you use a static mat ?

Send the busted ones back for analysis...

I had similar problem with PICMASTER emulator I did all kind of things
did not help. I removed the board out and installed in difference PC
worked ok. Even I
deleted MPLAB did not help. I reformat the hard drive reinstalled every
thing
boom? back to normal.
I gees Bill Gate has answer for you.
Hope this helps.

Wow. That's alot like my 5 step trouble-shooting guide to fix any software
problem.

1. Close and re-open the software package. If the problem persists:
2. Reboot the computer. If the problem persists:
3. Re-install the trouble-some software package. If the problem persists:
4. Format your hard disk drives. Re-install the OS, re-install the
software. If the problem persists:
5. Goto 1.

It really works!

       The kind of Summer we have had here in the Central United states
this year is more condusive to swamp creatures and mold.  It has probably
been almost 6 months since one could create lightning by scooting across a
car seat and touching the door handle.
I don't know how much ESD there usually is in Summer in the desert Southwest,
but most of the Central and Eastern part of the country has been in the
steamer.

We are having an unusually COLD summer this year, with borderline drought
until the last week or so.  Static has been a problem.

BTW, the geese are already migrating a few weeks ahead of schedule.  Think
they know something we don't?

I have seen static blow the bondout chips on the 16C74 pods but no
emulation memory failures. Is the failure real or is it failing the
diognostics. I have seen som spurious behavior where a pod fails the
diagnostics for emulation memory but runs fine. Check with the FAE or the
Factory. They may have a bullitin on it.

On a few occasions our PICMaster failed different tests in the
'Verify PICMaster' option. I noticed that you have to turn *everything*
off to get it out of that undocumented mode. Due to the interesting
PC interface design, you can actually keep your PC alive if you switch
it off with Mr PICMaster switched on (on its own power supply).

Bottom line : Switch *everything* off, go and make yourself coffee,
drink
it and have a good chat before switching it back on.
