While waiting 2+ hours and counting for a Fishhead-driven backup of my 2gs to
complete over Localtalk, I was wondering about the possibility of hacking the
drivers to use AFP-over-ethernet.

Has anyone managed to acquire the sources or a good disassembly of the GS
Appletalk support?

Tony Diaz has been able to get Appletalk working over a rare-as-hens-teeth
Apple ethernet card. Not sure if this capability was built into the GS
drivers, though.

I kind of doubt that would be feasible... I think the architecture of
that ET card is a lot like the workstation (serial) card, in that
there's a whole imbedded processor to deal with AFP. So there's a pile
of code that runs on that processor that is doing a lot of "driver" work.

How big is the drive you're backing up? ADTPro could do a whole volume
copy over Uthernet, but it would be suboptimal if the drive were
sparsely populated.

A good suggestion as any, but I think that's missing the point. Fishhead is
undergoing beta testing for its AppleTalk support.

I agree that a 2e would need coprocessor support, but I have to believe that a
2gs is natively capable in terms of computational power and memory.

I don't like image backups. A file-wise solution is important to me.

That might depend on how fast that 65xx processor is running on the
card. ;-) But a dump of the code it is running would be instructive.
It would take a chip reader of whatever sort of ROM device that card has
on it - the code isn't visible in the Apple II space. (From my
experiments with the workstation card.)

Understood, makes sense.

Is your goal to improve Fishhead, or are you just wanting an OTW backup solution?

If the latter, what about FTP (i.e. using Ewen Wannop's SAFE2)?

That would be the proximate motivation, but I was thinking also in the general
sense as an upgrade to Localtalk.

Can you do a recursive 'put' of the entire volume? I've never actually tried
that. But, even if that is possible I don't think ftp preserves file datestamps.
