	Yes it is possible. Your system must have a driver of the same density.

What was the original question?  (Cannot find it online here).  Point being,
the 3B1/UNIXPC/PC7300 can read/write/format all the following (which I've
personally tried, verified, and demonstrated to others):

5-1/4"	160K,  8 sec/trk, 40 trk, single-sided, single-density
	180K,  9 sec/trk, 40 trk, single-sided, single-density
	200K, 10 sec/trk, 40 trk, single-sided, single-density
	320K,  8 sec/trk, 40 trk, double-sided, single-density
	360K,  9 sec/trk, 40 trk, double-sided, single-density
	400K, 10 sec/trk, 40 trk, double-sided, single-density
	640K,  8 sec/trk, 80 trk, double-sided, double-density
	720K,  9 sec/trk, 80 trk, double-sided, double-density
	800K, 10 sec/trk, 80 trk, double-sided, double-density

3-1/2"	640K,  8 sec/trk, 80 trk, double-sided, standard-density
	720K,  9 sec/trk, 80 trk, double-sided, standard-density
	800K, 10 sec/trk, 80 trk, double-sided, standard-density

3B1/UNIXPC/PC7300-specific questions are best directed to both unix-pc.general
(which "may" soon be comp.sys.3b1 (depending on the current voting)) and to
comp.sys.att

If you're in Silicon Valley (SF Bay Area), many members of the AT&T UNIX Users'
Group own 3B1/UNIXPC/PC7300 systems.

Email me for more details (re: 3B1/UNIXPC/PC7300 or the Users' Group).
