I've had some problems writing to ProDOS disks recently, and wonder if it's
another symptom of the same problem.  I've been trying for a little while,
thus far unsuccessfully, to get a workable BinSCII disk for my IIgs.  On a
PowerMac 7200/90 running MacOS 8.6, I have file sharing disabled, and can
read and write ProDOS disks fine -- *except* for the file type, which is
always set to $00 no matter what I do.  I've tried stripping all resource
forks from the files and setting the HFS file type to "PDOS/text" as
recommended, but neither works.  On a Mac IIci running 7.6, however, it
seemed to work fine at least once (the IIgs returned gobs of "?SYNTAX
ERROR"s when trying to EXEC it, but I think that's an unrelated CR/LF
translation problem).

Of course, the older IIci has no Net connection yet, so my technique has
been downloading files via the 7200/90, copying them to a Mac floppy,
bringing them to the IIci, copying them to the hard drive, setting the file
type, and THEN copying them to a ProDOS disk.  Not exactly a fun task.
