Backdrop Plus 1.892 - This software is for Newton 2.0 Newtons ONLY. Backdrop Plus is an alternative to the NotePad as the backdrop, or background, application for the Newton. With the NotePad closed, you save as much as 10k in heap. This means that you can have more extensions and applications loaded at once, and you will get fewer memory-related problems and restarts. Each loaded application or extension takes up a small amount of heap. Since the NotePad is not used all the time, closing it when not used means there's more heap available the rest of the time. You should usually try to keep your heap above 35-40k after a restart (it will drop lower as you use your Newton. This is normal.)
