20 Year Timeline of the AS/400
The IBM Systems Magazine, Business Systems edition created a 5 page PDF with an illustration containing a 20 years timeline of the AS/400, now IBM i operating system on Power Systems hardware.
When I joined IBM in 1998, development of OS/400 V4R4 was on going and obviously there were support for a few previous versions already in the field. I remember that the IBM Guadalajara site still had some CISC systems in there for the support of earlier versions of the OS/400 and several products.
