Ditto, a MacOS program cannot access files on a Unix disk or partition. The more complicated answer is that you can run MacOS programs under A/UX if they follow all the rules. In this case they will access Unix files *as if* they were HFS files; this is what Jackie's "5 pound bag" was about. Apple should really put someone on this newsgroup who can do more than read the [wrong part of the] manuals and quote them to you. (Admittedly, reasonable people have posted, but Jackie's misinformation seems to be the default. Maybe Apple doesn't realize how bad this makes them look on the net?) But there is still no way to access *real* HFS files. In fact, to move a MacOS program into A/UX so you can run it, you have to take down A/UX, format a floppy as "MFS" (the cutesy user interface doesn't call it that, and I forget how you do it. Maybe click on "single sided" or something?), copy it onto the MFS floppy using the Finder, reboot A/UX, and use a little utility called "mfs" to move it to a Unix file! If you have a network (Ethernet, not that slow AppleWalk stuff -- which A/UX doesn't support anyway) then you can run the publicly-available-in- source&binary NCSA Telnet program under the MacOS, and move files to and from HFS disks onto a Unix system on your network. Then boot A/UX and rcp or remote-mount to get the files from the other Unix machine onto your A/UX file system. Wayne again: > I really need to know what kind of hard disk to buy with the Mac II!

Apple sells them for $2799 retail. We bought the exact same disk in better packaging for $1400 from Jasmine in San Francisco. Works great -- in fact, the A/UX beta testers were told to buy a Jasmine drive and then ship it to Apple to get A/UX copied onto it. Note the cool 100% markup if you buy it from Apple... We are also running A/UX on a 300MB CDC Wren-4. It works fine but the utilities supplied with A/UX for managing the partition tables are sad at best. It took us a night or two of decoding the doc and trying things before we could copy our A/UX 80MB disk onto the Wren and create a few more partitions to play in. I think this is the "non trivial" part Jackie mentioned. -- John Gilmore {sun,pacbell,uunet,pyramid,ihnp4}!hoptoad!gnu gnu@toad.com "Use the Source, Luke...."
