Singular Solutions A/D64x will work. Another product that will work is one I'm in the process of developing. Cost should be much less than the $1300 wanted for the A/D64x. I'll let everyone know when the prototype is complete. I'll either try to find a partner with capital to market the product or just sell plans to individuals that know their way around wire wrap and soldering irons.
