I have a 43p-260 and the system firmware loaded is called SPX03021. I
beleive this is the latest version, but according to IBM information this
firmware is for a system called 7043-260. My question therefore relates to
what the difference is between the 7043-260 and 43p-260 - are they the same
systems ?

To make matters more confusing, when I purchased the system (second hand)
the documentation referred to 9112-265 which again looks like a different
system.

Can somebody explain the difference between these systems so that I can use
the appropriate references in future ?

Thanks, Tim.
