Looking for AT&T Unix PC software

After hunting for what seems like ages, I finally acquired an AT&T PC 7300 today. In most ways it's fairly modest (40MB disk, 2 MB RAM), but I was very excited to find that it does have the Ethernet expansion card installed. I reset the root password and got into the system. It has the TCP/IP drivers loaded, and I'm able to do marvelous things like telnet and ftp on my LAN. Remarkable! My concern is that I don't have the TCP/IP driver diskette, so if anything happens to the hard disk, that's that. Does anyone have a disk image they'd be willing to send me? Judging from the FAQ, the part number is AT&T650008. I'd also love to find any other commercial software that was available. I could swear that there used to be archives of the stuff online, but if there were, I certainly can't find them now. Bitsavers has the stock system software, for which I'm grateful, but not very much else. Regards, -Seth Morabito
