It is reported that the Mac program 'ProTYPE' can be used as a helper
app to clean up the crud Macs add to files before copying them to an
Apple II. There was also another program to do the same, but it
disappeared recently from the net, which is apparently "normal" for
Mac ftp sites. ProTYPE is currently available online (at an Apple II
based site, so it hopefully won't disappear like the last rather
useful program) at
ftp://ground.isca.uiowa.edu/apple2/Mac/ProTYPE.hqx
Consult the various Mac FAQs for information on how to download and
use Mac programs. See section 1.3 of this FAQ for references on
finding other FAQs.
Some have said that you can apparently change the type and creator to
'TEXT' and 'pdos', before copying it to the ProDOS disk-- that'll
prevent it from adding the resource fork when writing to a ProDOS
disk. Others claim that won't do the trick for them.
Once you have the ability to download .bsq files and unpack them,
there are some Apple II files to remove forks. [These files are packed
with Binscii. If you don't have binscii because it's got a resource
fork on it, you can't use these fork removers. Thus, you'll need to
deal with it on the Mac end at first.]
HFS.LINK, listed above can apparently read out the data from either
fork; there are also the programs ConvertForks 1.0 or ForkSplit 0.5.
Also, the Apple //e emulation card (available for a few models of
Macs-- see the section on it) allows you to plug in a real Apple II
5.25 drive, and read files off of it.
5.10 How do I read/write Apple II files from an IBM PC?
IBM PC drives operate differently from Apple II drives at a hardware
level; there is NO software to overcome that. The only way to bridge
the gap with only a PC or an Apple II is by using (rare) addon
hardware. [Technical details: PCs use MFM disk encoding; Apple IIs use
GCR. The disk controller card does the decoding of the bitstream, and
if it's in the wrong format, it'll mess up the bits before software
can get anywhere near it. Thus, a new disk controller card is a bare
minimum.]
If you have a Macintosh and access to an Apple II with 3.5" disks
(such as most GSs), you can copy the files to a ProDOS disk and let
the Mac read that disk. It can then copy them to a MS-DOS disk with
the same software that read the ProDOS disks; see above for Mac
specifics.
Null modem is probably the best method; as noted above, the Crossworks
product from Sequential Systems is a good product that lets you
transfer and translate certain Apple II and IBM PC file formats.
There's supposedly a program that reads 1.44MB ProDOS disks on a PC
(which the PC does support), but you need the ability to write such
disks from the Apple II side anyhow.
There are a few rare hardware boards that you can plug into a PC and
get it to access Apple II disks; the Trackstar Plus and Quadram boards
are reported to be usable in IBM PCs. (Quadram's Quadlink reportedly
only supports the IBM PC XT and older; the Trackstar Plus works well
in any PC with space for a very full-sized ISA board and VGA
capabilities) Neither is available new anymore, and can command a
premium now on the used market, as IBM PCers who sold off their Apple
IIs realize the follies of their ways. :)
