OS400 emulator for Windows?

Many emulators exist to mimic a 5250 terminal with which to access an AS/400 running OS/400...

What exactly are you trying to do?

If you're trying to rehost an OS400 application on a PC, :shocked:
 
I did find (unbelievably... since why would you want your PC to emulate a mainframe?) a couple of mainframe emulators:


Hercules Version 3... Hercules is a software implementation of the System/370, ESA/390 and z/Architecture mainframe architectures. Hercules runs under Windows and Linux, as well as under various other Unix or Unix-like systems on Intel Pentium and other hardware platforms including Alpha, Sparc, and Mac.

A commercial product from 1998, FSI FLEX-ESL is based on the FLEX-ES ESA/370 'S/390 on Intel' emulator and when running under an Intel Pentium-II 400 MHz processor achieves approximately 7 to 8 MIPS of S/390 processing power. The FLEX-ES emulator allows you to use an IBM ESL license to run all the latest releases of IBM's mainframe operating systems including OS/390 2.6, VSE/ESA 2.3 and VM/ESA 2.3. Older releases of these operating systems are also fully supported.

No warped minds building OS/400 emulators that I've found... yet. If I remember correctly though if you're running VM on a machine, you can create virtual environments of any operating system... including OS/400.

So you could run Hercules or FSI FLEX-ESL, with a VM/ESA 2.3 operating system license, create and load an OS/400 environment under VM, and then load your OS/400 application. Maybe. Scary. :shocked:

Bear in mind you'd need to obtain the appropriate licenses from IBM in order to run modern versions of the operating systems, which could be very cost prohibitive. 😛

You'll probably also need at least a 9 track tape drive... SCSI attach drives for around $1,000.
 
Actually after a little more research the answer is no. VMWare will only run x86 type OSes.

Although after reading your post Hercules appears to be the asnwer for OS/390. Thanks Metron.
 
Cool... let us know how it works out.

Would be hilarious to find out that a modern desktop can pwn the "big iron"... even with an emulator.
