Connecting 9.2.2 iBook G3 to iMac with 10.4.9

Question

I've finally determined (tech support docs on 10.3.9 and online help do NOT make this simple to determine) that AFP ain't supported on 10.4.
Here is my current problem:
Open Public folder on iMac (10.4.9, Personal File Sharing enabled) using Chooser and the network icon on the iBook’s Desktop. File Sharing (or is it AppleTalk) Control Panel on the iBook has the "Applehare over TCP/IP" option enabled).
1. Open finder window to OS X drop box
2. Click and drag file to open window
3. Copying starts and progress dialog comes up
4. First error alert: The File Service's Connection Has Unexpectedly Closed Down
5. Dismiss that dialog and
6. "The Selected Files Could Not Be Copied Because the Server Is No Longer Connected."
I then installed Shareway IP Personal, latest version.
Restart iBook. I get the same error and error messages.
During all this time, a connection from iBook to a Blue and White running 10.3.9 remains connected and usable, as does the file sharing connection to an OS 9.2.2 Blue and White.
I'm a very savvy pre-OS X Mac user and a reasonably savvy OS X user, though simple file sharing in the house with OS X has become an exercise in bafflement.
The iBook is using an AirPort card through an Asante Wireless VPN Security Router, which is connected to my IP provider. All other Macs are wired.

Answer 1

Yeah, 10.4.9 broke Appletalk even further than 10.4.0 did!
I've been able, (using the old Shareway), to download either way, but not upload either way over a few KB.
10.4.9 copies from my OS9.2.2 machine to itself fine. OS9.2.2 copies from the 10.4.9 machine fine, but trying to put it either way will get that "no longer connected", and most of the time then freeze one or both machines until I reboot the OS9.2.2 machine.
