Ok, so I've bought my new Cas fx9750G Plus

1. Can you use only B&W pix or grayscales too?
2. If I d/l a game or prog for a cfx9850 (for example) is there any soft to convert is for the non-color calc (which otherwise is fully compatible) or should I write it?

3. What is casio assambler? It is possible on th 9x50 series too? A few links maybe?
Thanks!
