Sounds good!

I am not supporting this on the hardware side with my custom ROM Board because the required Flash chips are hard to get and expensive. I have never checked if this is something we could support via Einstein - it simply never came up.

I created the flash image on a Mac which has 8 mb of storage, and that is working for the most part fine, though the Newton reloads on it's own from time to time.  I've used that image on the Android version, which there unless I switch away from Einstein for more than a few minutes, will stay up till I quit out of it.
