DDS Products

DDS products are availale in both the original DOS/Win32 releases, as well as DVM/Win64/Linux releases. Both releases are included with one purchase.
For pricing and/or information on how to obtain these, refer to my catalog.

Dunfield Virtual Machine

This is a virtual machine which I created to be able to compile and run most of my products and tools under Win64. It does this very well. Windows (and now Linux) editions are free on this site. Check it out!

Very simple, does NOT have to be installed. One executable file, no extra supporting libraries etc. required.

It could also be very useful to provide powerfull "scripting" abilities to other products, or the ability to let users run more complex programs completely under your control. If this sounds interesting to you, contact me and we can discuss options.

DDS MICRO-C Developers Kits

These are complete PC based cross development systems which include EVERYTHING you need to develop 'C' and 'ASM' software for a CPU.

Includes MICRO-C compiler, optimizer, assembler, and related utilities.
Hand coded (efficent ASM) standard library for CPU (Source included).
Includes Monitor/Debugger for CPU - ASM source (See XTOOLS)
Includes text editor, MAKE and many other utilities.
Complete documentation (on disk).
Lots of "extras".
Available for: 68HC08, 6809, 68HC11, 68HC12, 68HC16, 8051/52, 8080/85, 8086, 8096, and AVR families.

The free DVM package and compiler give a decent example of how a developers kit works in practice.

XTOOLS: Cross assemblers, Disassemblers and Monitors

ASSEMBLERS

6800, 6801/6803, 6805, 6502, 68HC08, 6809, 68HC11, 68HC12, 68HC16, 8048, 8051/52, 80C320, 8080/85, 8086, 80186, 8096, Z8, Z80, AVR, H8, ST7, 16C5x.
Output files in either INTEL or MOTOROLA hex format.
Plenty of features and options.

DISASSEMBLERS:

These are "smart" disassemblers with many features to assist in the generation of complete symbolic/commented ASM source from binary machine code.

6800, 6801/6803, 6805, 6502, 68HC08, 6809, 68HC11, 68HC12, 68HC16, 8051/52, 8080/85, 8086, 80186, 8096, AVR, and H8.
Generates listing or ASM source format output file.
Accepts user defined symbol table. Can build initial symbol table from references occurring within the input code.
Accepts file of comments to be merged into the disassembly output.

MONITORS:

68HC08, 6809, 68HC11, 68HC12, 8051/52, 8080/85, 8086, 8096, Z80 & AVR.
Well documented ASM source code.
Completely stand-alone, runs on the bare hardware.
Very compact, occupies less than 8K of ROM.
Built in disassembler (except AVR).
Edit/Dump Memory, Processor registers and Interrupt vectors.
Multiple breakpoints, which are completely transparent to the user program, and remain effective until removed.
Software Single-Step works even when tracing ROMed code.
Download INTEL or MOTOROLA format hex data.
Revector any/all interrupts to the user program.
Online help display of commands and syntax.
Many more features *** Features may differ in some monitors.

Bonus! AT: Assembly Translator A program to assist in the translation of assembly language code from one CPU to another.

Uses pattern matching and lookup tables to translate code written for one CPU into code which can be used on another.
Works with any CPU, you define the translation tables, and compile them into a working translator using the supplied ATC (AT Compiler).
Include sample translation tables for 8080->8086 and 6809->8086

UTILITIES:

MACRO - Powerful ASM source macro pre-processor.
CREF - Cross-references symbol usage in ASM source file.
PSOURCE - Protects distributed source code.
RETAB - Retabulates output file to specified tab stops.
HEXFMT - General HEX file manipulation, including: - Calculate checksums over all or part of code file. - Reformat output record type (INTEL/MOTOROLA/BINARY) & length. - Change base and load address of code image. - Remove strings of $FF (unprogrammed) data bytes. + Utilities for converting to/from other popular assembler formats.';

PROJECT PLANS

This package include all of the necessary schematics, software and documentation to construct the described devices (contains no hardware):
