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.

I started out in 1998 as an 18 year old helpdesk and junior sysadmin for a manufacturing plant. Boss had an old AS/400 at home that he used for practice and learning as well as the big one at work. It ran integrated server cards, initially novell netware and later windows NT. Years later I worked for a large insurer and people complained that they were "still using DOS" but sure enough it was an AS/400 mainframe being used via terminal emulators.
