Way back in 1993 I got my first experience with an IBM AS/400 system.
Somewhere around 2010 I got my own first small AS/400 system.
I think that in twenty or thirty years these systems will be gone for the most part. And I made a choice to start to preserve them.
You can find more info about this hobby at my website www.as400museum.org.
Sometimes I even exhibit these systems, for example at the yearly German vcfb.de event. Come look me up there some day!
