We are hearing of hacks to provide 1Mbyte of memory for the Mac.
One of the best ways of using this memory is to have 512k for programs
and a 512k ram disk.

Doesn't this mean that there is a niche for an external ram disk?
This would suit better those of us who don't want non-Apple approved hardware
intrusions.
I would much rather pay for a ram-disk than a second floppy drive.
You could boot off the ram-disk (by setting it up from the floppy and hitting reset).
Battery backup ought to be straightforward. 30secs is enough to transfer
the ramdisk to a couple of floppies.

Two questions:
	Is anyone doing such a thing?
	What performance limitations does the hardware interface have to
	the second drive? I am assuming that 0 seek time provides the most
	benefit.
