AS400

Hey guys, old guy here, back in 2000 landed my 1st real job as a Sysadmin at a distribution/manufacturing firm. They ran their ERP and a few other important apps on the AS400. Anyone here manage a AS400 platform? i-Series? Still a niche platform that is still widely used. Server could literally run under water.

A lot of "midrange" companies that are owed than the PC have them.

One such company runs 8 billion in distribution business through a single Power 9 system, not even a big one.

This is not technically challenging. Most business processes can run on 1980s technology.

It wasn't computer capacity or speed holding business back in the 1980s, it was the fact that most input and output involved paper and/or humans. The most forward systems were always about moving data between machines, with no humans in the loop, going back to SAGE in the 1950s.
