	Netters: I hope you can help me.

	We have some installations in the Canadian Arctic that keep
	destroying their hard drives.

	We have decided the problem is the speed at which the temperature
	in the huts vary. We can't rebuild the huts. Our intended solution
	is to change over to solidstate (RAM) disks.

	1 - I don't mean putting some system memory aside and putting a file
	    system on it.
	2 - I mean a physical device that looks like a 5-1/4 inch winchester
	    that has no mechanical parts in it. It is nothing but ram.
	3 - I know of two companies selling these for SCSI - Western Automation.
							     Vermont Research.
	    As far as I can tell they are both selling the exact same product.

	a Company used to sell an ST506/412 ramdisk called BATRAM, they don't
	any longer.

	What I would like is : 16 MegBytes or greater
			       ST506/412 MFM drive
			       battery backed up

	Information on any such product would be a live (money) saver
	as our only alternative is to purchase the SCSI drives and
	a SCSI controller for multibus I (approx 2K per controller).
