Editing IBM Future Systems project (section)

== Results ==
Although the FS project as a whole was terminated, a simplified version of the architecture for the smallest of the three machines continued to be developed in Rochester. It was finally released as the IBM [[System/38]], which proved to be a good design for ease of programming, but it was woefully underpowered. The [[AS/400]] inherited the same architecture, but with performance improvements. In both machines, the high-level instruction set generated by compilers is not interpreted, but translated into a lower-level machine instruction set and executed; the original lower-level instruction set was a CISC instruction set with some similarities to the [[System/360]] instruction set.<ref>{{cite web|title=The Library for Systems Solutions Computing Technology Reference|url=http://www.redbooks.ibm.com/redbooks/pdfs/gg244100.pdf|publisher=[[IBM]]|pages=24–25|accessdate=2010-09-05|archive-url=https://web.archive.org/web/20110617120008/http://www.redbooks.ibm.com/redbooks/pdfs/gg244100.pdf|archive-date=2011-06-17|url-status=dead}}</ref> In later machines the lower-level instruction set was an extended version of the [[PowerPC]] instruction set, which evolved from John Cocke's RISC machine. The dedicated hardware platform was replaced in 2008 by the [[IBM Power Systems]] platform running the [[IBM i]] operating system.

Besides System/38 and the AS/400, which inherited much of the FS architecture, bits and pieces of Future Systems technology were incorporated in the following parts of IBM's product line:

* the [[IBM 3081]] mainframe computer, which was essentially the top-of-the line machine designed in Poughkeepsie, using the System/370 emulator microcode, and with the FS microcode removed and used
* the 3800 [[laser printer]], and some machines that would lead to the [[IBM 3270|IBM 3279]] terminal and [[GDDM]]
* the [[IBM 3850]] automatic magnetic tape library
* the [[IBM 8100]] mid-range computer, which was based on a CPU called the ''Universal Controller'', which had been intended for FS input/output processing
* network enhancements concerning [[VTAM]] and [[IBM Network Control Program|NCP]]
