All products are availle as 16-bit applictions which run under DOS or Win32.
These also work well under DOSBOX.  DOSBOX is available free.

Many of the products are also available as DVM applications, which run well
under Win32/Win64.  DVM is a much simpler and faster virtual machine which
does not require installation, and works directly on the host file system.
A free windows version is availble on my site.

See the download section of the above web site for DVM and also the version
or DOSBOX that I recommend.

The free DVM also has a free MICRO-C development package which works quite
well as demonstration of how a MICRO-C toolset for an embedded system works.


DVM: the Dunfield Virtual Machine A product to enable others to have powerful programmable subsystems. If you have a product that could benefit from a powerful "scripting" language, or any other ability to let users run code totaly under your control. If you don't want to add one of the massive and complex tools that exist (java?) to your product, and if you don't like the idea of spending time (and money) creating and testing something new, this could be what you need. See the free windows DVM in my download section for more information. The core of DVM is written in standard GCC and does not rely on system libraries. Price : Contact me to work out what you want/need. Availability : Can be made to run "most anywhere". Note: The DVM name and the appearance of its various tools does not have to appear as is (or at all) in your product. I can provide services to customize and adapt it to your liking.

If you wish to obtain some of my products, please contact me. We can arange payment via E-transfer or PAYPAL, and I will send you an encoded .ZIP file containing the software (encoded because most products contain executable files and many ISPs won't allow executable files in attachments).

You will need "DECZIP" which is available on my download page.
