Alfred's advice is "dead on" and i couldn't agree more. Be advised a small rant to follow.


If a business can't afford a commercially available programmer such as the inexpensive DATAMAN or it;s like that same funding restriction will also impede the fabrication, service, and design of products and the customer will pay.

Now i don't mean to preclude the next HP inspired garage shop and custom programmers can be made that exceed the capability or specification of existing solutions but if it's not to sell the next great commercial burner shouldn't you be working on your product?

Now building for the home shop is excellent way to acquire or express skill. So i would suggest building a "targeted" burner that exploited Alfred "programming" suggestion however i would build it with lot's of growth potential as you acquire new "targets" and design the single transistor voltage translator, or the new timing routine that allows the existing design to "evolve" into the new target. In time you will build the programmer that has just what you really need and the solutions are "attacked" 1 by 1.

Are you familiar with DACs conceptually?
