Distribution Notes 68000 Assembler/Simulator 8/4/89 Version 1.0 DESCRIPTION: This product is meant to provide a learning tool and/or a useful cross-development tool for people doing MC68000 software development. It contains two separate programs: 1. A 68000 cross-assembler which produces text output in S-record format suitable for downloading to single-board 68000 computers or PROM burners. 2. A 68000 simulator which allows debugging of the 68000 source by reading the S-record output produced by the assembler. The simulator mimics the operation of the 68000 microprocessor as documented in the 68000 Programmer's Reference Manual. The source code is provided for several reasons. The user may want to modify the programs' behavior, add features of his own, port the programs to different machines, or fix bugs if they come up. These programs were written at North Carolina State University's Electrical and Computer Engineering department. CONTENTS: The contents of this disk are as follows : EXE.ARC -- Executable files and user manuals ASM-SRC.ARC -- Cross-Assembler's C source code SIM-SRC.ARC -- Simulator's C source code TST.ARC -- Sample 68000 source files PROBLEM WITH THE SIMULATOR: There is an undocumented problem with the simulator. It won't allow use of the memory between addresses 1000 (hex) and 1003 (hex) inclusive because those are the addresses that the simulated 6850 chip maps its registers to. The 6850 is was implemented in a previous simulator version but has been disabled for this version. The simulator's address space is 64K of memory from address 0 to address FFFF (hex). DISTRIBUTION: The contents of this disk are public domain. You may use the source code in your applications, and you may copy and distribute the disk freely with the notable exception that you may not charge more than a minimal handling fee for distributing it. NOTES ON THE SOURCE CODE: The two programs were originally written on a VAX 11/750 and later ported to the PC. The source code provided on this diskette was compiled with the Microsoft C 5.0 compiler. It should be possible, of course, to compile this code with any C compiler that uses 16-bit integers with minimal modifications. VAX source code is available by contacting me at the address below.
