Disk upgrades for 3b2/310

[kaplan at uiucdcsm.UUCP]

Has anyone out there in netland gotten a 3b2/310 with 30Mb disk and later
tried to upgrade to a larger disk and/or install a second disk.  If so, I
would like to get some info about how much this costs, who the suppliers
are of the upgrades (perhaps only ATT?), what size disks are available,
etc.

Any information will be helpful.  My email addresses are:

or
	kaplan at m.cs.uicu.edu

Thanks in advance
