But how about with Megaram alone?
What's the use for a megaRAM alone, if it's normal RAM based
(clearing data with power-off)? Don't you always need another drive
to save the data more per

You might even include this in a add-on ROM, so that a non-DOS2 using

Or: modify a DOS2 ROM, so that you could use its mapper support,
without DOS2 file system.
