The #ibmi timeline up to date

What an amazing story ...

System/3	1969-1975	Product of General Systems Division, formed as result of anti-trust legislation. Low-end batch system replacement for unit-record equipment. Used RPG programming language. Disk and terminals soon added. 28-instruction CPU. Over 25,000 sold.
System/32	1975-1977	System/3 follow-on.
System/34	1977-1981	System/32 follow-on. Ran SSP OS.
System/36	1981-1986	System/34 follow-on. Ran SSP OS.
System/38	1978-1988	Pioneering design, revolutionary architecture system, continued in AS/400, iSeries, System i5, IBM i to date, provides complete insulation for user applications against technology change. Also, first system line to include in-built relational database system. Ran CPF OS.
AS/400	1988-2000	Repackaged and improved S/38, hugely successful in medium business markets, using S/38 architecture. By mid-late 1990s, became open, e-business capable server. 200,000th AS/400 sold by 1992. OS/400 OS. From 1995 based on RISC chip (PowerPC).
iSeries	2000-2002	Repackaged and re-branded AS/400, under eServer strategic initiative.
New iSeries	2003-2004	Radically reshaped and extended, repackaged and re-priced iSeries, repositioned as "On Demand" e-business hub platform consolidating Windows/Intel, Linux, AIX, Java and Domino (as well as traditional OS/400) workloads. Over $500M IBM investment.
System i5	2004-2007	Technology convergence with pSeries, including AIX in a partition. Operating system now called i5/OS.
IBM i on PowerSystems hardware	2007-	No distinction between i and p hardware - all just Power Systems. Operating system now called IBM i.
IBM i on PureSystems platforms	2012-	Expert integrated systems: ranges of infrastructure and application platforms with full support for IBM i workloads.
