Snow: Created page with "'''Silverlake''' was the codename for the AS/400 project, named after Silver Lake, Minnesota. It was a skunkworks project created as failsafe in case the Fort Knox project failed, which it ultimately did. Prototype machines were known to have existed and possibly seeded to third-parties; these machines bore the 9384 machine type but were otherwise visually identical to the released AS/400 machines. <gallery> File:9384-Proto.jpg|A promo photo of a 9384 prototyp..."

This list is separated by generation. The grouping is unofficial, but each generation of workstation was released to roughly coincide with major releases of machines. Unless otherwise noted, all workstation generations are forwards and backwards compatible across all twinax-capable platforms, with some unsupported features depending on the host they are paired with.

5250 Emulation

2025-10-10T13:00:03Z

Snow:

This page covers various emulation options for the 5250 and TN5250 protocols.

== Emulation Boards ==
Hardware emulation boards natively speak the 5250 wire protocol and will work across every midrange generation that spoke twinax. All hardware twinax cards have their own bespoke emulation software, and cannot be used with another vendor's software. If the software is not available, the card cannot be used so if you have a copy please get in touch with us.

This section is targeted at 5250 emulators that speak the TN5250 network protocol. This means these emulators are only compatible with an AS/400 running V3R1 or later. Older versions of OS/400 and SSP may also be usable if connected to a compatible AS/400 with [[Passthru]].

'''System Support Program''', commonly abbreviated to SSP, is the operating system used on the [[System/34]] and [[System/36]] midrange computers, and in the [[Advanced/36]] emulation environment for [[OS/400]]. It is an evolution of the operating systems found in the [[System/3]] and the [[System/32]], and was designed for source code compatibility with both prior machines. Applications were typically written in [[RPG II]], with support for BASIC, FORTRAN, and an assembler available. Scripting and batch processing was typically handled via the use of [[Operational Control Language]].

System Support Program originated on the System/34 in 1978 and was supported until Release 9. Its only user interface was an OCL command line at the bottom of the screen.

The System/36 version of SSP added the familiar menu-driven user interface and support for lowercase characters in user applications, including the operating system itself. Later versions of SSP would also support the [[DisplayWrite/36]] application and [[PC Support/36]], as well as extra hardware options such as tape drives and token-ring support.

The final version of SSP was Release 7 and was exclusive to the Advanced/36 emulation environment. It was modified so that the operating system depended on certain low-level functions of the PowerPC AS processor and the emulator software and as such does not run on an actual System/36. However, the userland of SSP Release 7 is the same as Release 5, so any existing System/36 application could continue to run, unchanged. Advanced/36 and therefore SSP support ended when [[OS/400 V4R5]] was released, which dropped all support for the Advanced/36 emulator.

IBM continues to support SSP applications on [[IBM i]] through the use of the System/36 Execution Environment, a special set of compilers that will compile System/36 RPG II source code to a present-day IBM i application. Notably, this does require that source code is available as the Execution Environment does not emulate a System/36 and cannot run SSP executables.
