Marilyn, Try "The Massive Developer Chart" at http://digitaltruth.com/devchart.html They have Maco films, but not the name Genius. You may recognise it under another specification. To all interested in any B&W films, this is an excellent startign point for any film/developer combination, worth while bookmarking.
