SneakerNet, with a pass-thru a Mac that handles floppies or Zips
Nope. That won't be happening either.

Since Snow Leopard only reads HFS, there will be no writing to disks, external 1.44MB floppy, ZIP or otherwise for use with any Mac which cannot run System 8.1. That rules out all the Compacts (with the possible exception of the 8.1 hack for the SE/30 and possibly CC/CC II & Classic II), which is where this topic is posted.

So no, Apple has effectively eliminated Snow Leopard as a practical platform from which to maintain a vintage Compact Mac. A suitable emulator like Mini vMac should allow disk images to be manipulated and then read directly into ZTerm for serial modem transfer, however, there is no way to write those files to a physical HFS disk in order to use the "SneakerNet" (that is sooooo 1984). In fact those files under Mini vMac will already have to exist on HFS images in order to even get them into Mini vMac (which does not yet support OS 8.1). In the interim, SheepShaver can be used (the latest 2006 build still mostly works under SL) to read HFS+ disks and transfer them to HFS. However, anything that can run 8.1 will also not be able to work with MFS disks, so keep Mini vMac handy (much more stable under SL anyway).

FTP works from the Mac Plus forward, thought not as elegant as AFP. Just out of curiosity, we know for sure they have dropped support for AFP 2.x and earlier? I know AFP 3.0 corresponds with OS X, but it had roots in OS 8 & 9, right? So did they essentially remove AFP support prior to the introduction of HFS+ with 8.1? If so there's an interesting parallel with dropping AFP on any System which did not support HFS (i.e. 128K/512K & MFS). Perhaps AFP 3.0 requires HFS+ files structures only to be optimized?

Here's an interesting articleabout losing legacy support under SL.
I'm confused by what you mean about dropping AFP. AFP has never been dropped. AFP is just another name for AppleShare. AppleTalk has been dropped as a low level protocol, and replaced with IP, but AFP (AppleShare) is still with us. Nevertheless, 10.6 seems to require AFP 3.0, and dropped support for AFP 2.1 and 2.2 (Which could use IP instead of AppleTalk).

Mac128, have you gotten the new build of SheepShaver from 2008? It's at this link.

Random notes:

Mac OS X will let you format a USB floppy with HFS+. Classic Mac OS would never let you do this. HFS+ floppies can be read by System 8.1 and up.

Classic Mac OS let's you share USB floppies over AppleShare, but won't share internal floppies. Mac OS X won't share USB floppies.

What's happened to HFS disks mirrors what happened to MFS disks. Starting with 7.6, MFS floppies were read only. 6 months laster, by System 8, they were unreadable and ejected upon insertion.

My gut feeling, Mac OS 10.7 will require a 64-bit Intel processor, will not support Rosetta (optional already in 10.6), and not read HFS disks.

10.8 drops Carbon apps. The transition Apple is trying to make will be compete! :lol:

Just my two cents. Thoughts everyone?
