RE: Named PTF's - was CPF324A -- MIDRANGE-L

I thought that was why the memory cards were so huge, b/c they have a lot of
error-check chips on there???

On that note:  Did you ever hear about the "gamma-ray" PTF?

This may be stuff of urban legend, but I heard about it in the mid-90's, I
believe...

Apparently some AS/400 customers were having intermittent problems with
their systems crashing.  After investigation, it was found that if the
system was located above a certain elevation, gamma rays would zap memory
bits between refresh cycles, causing the system to go down.

The  fix was a PTF that caused memory refresh to occur more frequently
