Good to hear that you arrived at your intended destination. My own Classic IIs are full-time members of my LAN, through a newer Desktop EN/SC (fixed SCSI ID=6, and inbuilt SCSI termination) and an older EN/SC (larger, with selectable SCSI ID and dual DB-25 ports). Given that, who needs floppy disks any longer? You may or may not find that the interposition of a 10Base-T hub between the EN/SC and the remainder of a LAN is an advantage. Decent Gigabit and 10/100 switches will play 10Base-T as well as 100/1000, but the hub can be the clincher/ameliorator for connection and reliability.
