Thank you Mk.558. Your site is an amazingly detailed resource. Just spent a few hours and tried a whole bunch of things and nothing came from it, sadly. Looked at your "AFP" table first, and humbly see that 7.5(.0)'s highest compatible match seems to be 10.2, perhaps? But based on your recommendation, I kept sifting through your walk-throughs, including the "MacTCP" and "Mac OS X 10.5 Leopard" sections, and thought I was getting close. One thing I was not able to "see" was an "Options" button under "File Sharing" and the "File Sharing" checkbox, so looks like I'm somehow not able to share files using AFP. I proceeded to designate some folders for sharing but, alas, nothing is showing up from either mac to the other. Will keep reading through your work, thank you for being so detailed.
MacTCP does
not provide AFP over TCP capabilities by itself. It's a common misunderstanding, and it doesn't help that people frequently associate MacIP with AFP over TCP/IP. It's a reasonable thing to assume, and as I don't want to confuse you, I won't go further into it without you requesting it.
The Chart has a few errors. The next major release version will look very similar to this:
If you want to continue using 7.5, which would be smart for speed reasons, then you'll have to use FTP.
If you want to use AFP for speed and ease of use, the easiest thing to do is install Mac OS 8.1 with AppleShare Client 3.8.3, which will work just fine with 10.5.
Of course you may have a chicken and egg problem: how do I get stuff
to the 7100/80 if I can't get stuff
off it. FTP could come handy once again. If you have a working CD-ROM drive, you can install an OS that way.
If the 7100/80 has just 7.5 installed with Classic Networking (that is, it uses MacTCP) then you're stuck at 10.3 at maximum (Panther would mount the 7.5 box, not the other way around).
It would be helpful to know what is already on the 7100/80s hard disk for network stuff, such as FTP clients.
There's a couple of ways to go. To set up Ethernet, you just need the AAUI dongle attached, a straight RJ45 cable to the router plugged in. Head to Network control panel and choose Ethernet. Head to the Chooser, if AppleTalk is on, which it should be by default, then click AppleShare. Because 10.5 cannot share to systems this old, we'll have to get more information on how you'd like to proceed.
