All In addition to www.z390.org Portable Mainframe Assembler and Emulator, here is a really simplified assembler loader and emulator that you can run on the web: www.idiac.org. IDIAC was developed for educational purposes. It has just 10 different instructions and yet it can be used to calculate Pi, perfect numbers, etc.

Does anyone know if there is anything like this (below) for the z ISA? It is a basic assembler, no macros, where you code MIPS assembler into a text file, then load it into the emulator. The code is compiled. You are then in a "debugger" in which you can run the code, or single step. It's quite nice for learning the basics of the ISA. http://spimsimulator.sourceforge.net/ [quote] *Spim* is a self-contained simulator that runs MIPS32 programs. It reads and executes assembly language programs written for this processor. *Spim* also provides a simple debugger and minimal set of operating system services. *Spim* does not execute binary (compiled) programs. *Spim* implements almost the entire MIPS32 assembler-extended instruction set. (It omits most floating point comparisons and rounding modes and the memory system page tables.) The MIPS architecture has several variants that differ in various ways (e.g., the MIPS64 architecture supports 64-bit integers and addresses), which means that *Spim* will not run programs for all MIPS processors. *Spim* comes with complete source code and documentation. *Spim* implements both a terminal and windows interfaces. On Microsoft Windows, Linux, and Mac OS X, the *spim* program offers a simple terminal interface and the *QtSpim* program provides the windowing interface. The older programs *xspim* and *PCSpim* <http://spimsimulator.sourceforge.net/older.html> provide native window interfaces for these systems as well.

Microfocus used to have one. It was good enough to get ALCS running on a PC. There's a few open source projects. z390 and, of course, Hercules, spring to mind. I think there's one built especially for education too, but its name has long since slipped into the murky depths of what passes for my memory. i On Wednesday, April 22, 2020, 12:53:53 PM GMT+2, John McKown <[email protected]> wrote: Does anyone know if there is anything like this (below) for the z ISA?
