Monobath developer for Direct Positive Paper

I am interested in monobath developers, especially for giving a photographic demonstration to elementary school-aged children. I would like to show them how a light sensitive surface can be exposed in a camera, and then developed to reveal an image. I will likely end up using cut film in my Speed Graphic, and processing with a tupperware of monobath (R3/Donald Qualls formula) to demonstrate.

It would be even better to have a positive image to show at the end of the process. That leads me to Harman's Direct Positive Paper.

Is there a monobath formula that would work with Direct Positive Paper? Bob Crowley mentioned on the New55 blog that such a thing existed...

Monobaths are as I'm sure you realise aimed at film rather than paper, and film and paper developers are formulated slightly differently.

On the other hand, HArman DP paper is inherently rather high contrast (or at least the last lot I used was) and might benefit from the lower contrast you might get from using a film developer for it rather than a paper developer (just a vague thought, not a scientific deduction)

My guess is you will be best off to start with a basic formula and tweak it to your requirements as you go.

there've been many discussions of monobaths at APUG, the most recent is here: (there was a url link here which no longer exists) , where you'll also find a formula.
