I worked with AS/400s. Very fond memories of changing the backup tapes, in particular. I loved the server room! Meanwhile on the software side I was mostly dealing with EDI messages and it was all about critically precise placement of characters (including whitespace). It was ... weird. Nice machines though. The whole company's back office systems for around 300 shops ran on two of them in head office. Ah nostalgia...
