I've a 80MB disk (marketed by Jasmine, but with a Quantum mechanism) left
over from my Mac days. Using "scsimodes" I have no problems seeing the drive
and have contemplated installing it as a swap disk. The question is - is it
worth it or should I just try to sell it and get more memory instead? My
current cube configuration is:

	'030 cube, Version 1.0 software
	8MB memory
	Fujitsu 680MB drive
	Optical Drive

I'm just using the optical drive for backups. The pros I can think of are:

	Cut down on thrashing on Fujitsu drive

The cons are:

	Reliability?
	Yet another device to reach around behind to power up before the cube.
	80MB has av. 28msec access time, the Fujitsu claims 16msec. Will it
	actually be _slower_ to swap to the 80MB? 

I realize that I really need more memory so my inclination is to sell the drive
and use that money (hopefully around $300?) towards getting it. Is it correct
that I have to get memory in sets of 4 (i.e. a minimum of 4MB using 1MB SIMMS
or 16MB using 4MB SIMMS) ? Suggestions welcome.
