Apple II software in a .2mg image format and a 68k Mac
madmax2069
I am new here and hope you can help me with my little issue.
I own a Apple IIgs (i have blank disks but no software)
just about everything online is stored as a .2mg image file.
now i do have a Performa 475 that i did use to format a few 3.5"
disks to prodos 800k. i also downloaded the install disk 1 of GS/OS
(uses a Mac SEA from Apples FTP), i then made a disk out of that
which works fine.
used another disk to copy a tools to install onto the disk ( asimov,
shrinkit gs, BScit, and a few other tools) all of those was in a
shrinkit archive format.
now the issue is that most of the .2mg unzip or unstuff to a few k
over 800k ( too big to fit on a 800k floppy disk to use asimov) and
so far i have not been able to find any software that will work with
.2mg files on a 68k Mac running OS 7.
question is
Is there any software for a 68k Mac that will work with a .2mg or to
convert it over to where disk copy 4 can use. because right now this
is the only way for me to transfer data over to the IIgs.

I think your best bet would be to build a floppy that has all of the
Appletalk software on it, turn on file sharing on the Mac and then
access the .2mg files that way. I seem to recall that you can't fit
Finder on there with the necessary tools so you'll have to use the
simple launcher program.
It's been way too long since I've done file sharing with only floppies
available, so I'm not certain about what needs to be done. And I don't
have room to set up my GS to play with...

The approach I've used is to convert 2mg files to whole disk sdk
(ShrinkIt) files on a PC within an emulated GS environment on the PC.
I then transfer those to my Mac Color Classic via 720K DOS floppies,
which works if your Mac has PC Exchange installed (OS version 7.5 if I
recall correctly). I then copy the sdk files to ProDOS floppies to
transfer them to the GS, and use ShrinkIt on it to write them back to
physical media. The process is a bit of a pain, but it works and I've
used it to create in excess of 100 disks for use on the GS.

The bad thing is that i dont have a PC that has a 3.5" drive in
it.
the way i can try to do that is somehow convert the image using a
emulator (what emulator do you recommend) i do have activeGS, then
upload that to a file host in a .zip form. and download it onto my
Performa 475.
the thing is i need a way to get the converted image off my PC and
onto my 68k Mac.
i need to work on the steps of how to make sure that i can unstuff the
zip file that the PC makes so that the Mac that is running OS 7.6.1
can use. and find a file host that wont bork up the file.
i do have a few tools that will work with .2mg files (ciderpress) and
can convert them. i wonder what format (that ciderpress can convert
to) would be best.
Thanks for the help so far.

Interesting
The only thing is i lack the hardware and cables to hook my IIgs upto
the Mac (or router even). the LC 475 has a Ethernet card but i lack
any serial cables to hook up to the IIgs. and i don't have Ethernet
on the IIgs.
that ideal sounds great if i had the proper hardware and cables.

And you'd be set.
Or you can get the phonenet adapters for less cost and use a standard
RJ-11 phone cable (needs to be 4 wires), but the phonenet adapters may
not come with the needed terminator and you might have to build one
yourself. (The localtalk box self-terminates.)

ActiveGS is the one I've been using, but the process I described isn't
the simplest possible one, and your post reminds me of that.
Ciderpress itself can generally be used to convert a 2mg file to an
sdk archive in most cases. Once you have that, you can zip it up and
transfer it to your Mac using the process you described.
Using an emulator (for me) was useful in that it allowed me to try out
the software before jumping through hoops to get it transferred to my
IIGS. If I decided I wanted to transfer something, I'd boot up
ActiveGS with an emulated hard drive, insert the 2mg and use ShrinkIt
to create an sdk file somewhere on the emulated hard drive. I'd then
exit the emulator and use Ciderpress to extract the sdk file from the
hard drive image for transfer.

CiderPress can convert to the DiskCopy 4.2 format. Sounds like you
might be able to use that directly on the Mac (assuming all the fun
stuff with file types and resource forks works out).

using ciderpress is still a bit hard for me to figure out, i will
eventually get it.
making a .zip and transferring it over to the Mac is one of the spots
i am having issues with. since i am using a 68k Mac running system
7.6.1 trying to unzip the file fails.
what program are you using on windows to make the .zip (if you are
using windows). I tried using winzip but the Mac i have wont unzip
them.
i dont know if its because i am using a newer version of winzip or
what.

I mentioned zip files simply because I thought that was your
preference, but I don't use them myself for transfers to the Mac.
Instead, I simply transfer the sdk files directly to the Mac, since
they are already compressed archives. On the Mac, I have installed a
freebie file type changer that let's me drop the sdk files I've
transferred onto its icon, and it figures out what the ProDOS filetype
should be and sets it appropriately. I then copy the sdk file to a
ProDOS formatted floppy and use that to get it to the IIGS, where I
can use ShrinkIt to open it and create a working disk.

With a USB adapter and a null modem cable you could hook a modern
computer to the GS and dispense with all the extra steps - ADTPro
could just send the .2mg files directly to the GS' floppy drive.
Or, as Andy McFadden pointed out, CiderPress could strip the .2mg
header off the image and make it palatable to DiskCopy. But that's
more of those steps...

We are talking about a old 68k Mac running OS 7.6.1, not a PPC Mac or
intel Mac running OS X, ciderpress for Mac requires OS X (Thats a bit
of a tall order for a 68k).
I did find out why the .sdk files wasn't working in GSOS though. all
it took was a program called Prodosifier to fix most .sdk file type.
i was able to download Revenge Of The Bobs in sdk form, put it on the
disk and used ProDosifier to fix its file type. and used shrinkit in
GSOS to make a disk.
But that don't help me with .2mg files. Even if i was to convert the
image using ciderpress to a diskcopy 4.2 file, i still have to
compress it to keep it from getting corrupt when i upload it to a
http file host.
I use a http file host so that i can download it with the Performa
475. I have tried many times and the file (if i don't compress it) is
unusable. when i do use winzip to compress it i have no way on the 68k
Mac to unzip the file. like i said maybe its because the version of
winzip i use on my PC is too new for the Mac to unzip (using stuffit
expander, or Maczip) and tried winrar with macrar and it would not
detect it as a rar file.

I'm confused. Doesn't the Performa 475 have a 1.44MB floppy drive?
And, if so, can't you create a 1440K ProDOS image, copy your 801K SDK
image to it, then write that to a 1.44MB disk to read in the Performa?
Just a thought. That would be easier than uploading them and then
downloading them again.

Yes, I see that error. I was going to say 2MG, then changed it to SDK.
The SDK images can be smaller and may be able to fit more than one. 8^)

The 8-bit ShrinkIt has an option to open *any* file type--just press
Open Apple-A IIRC, and you can choose any file. ShrinkIt doesn't really
care about the file type of an archive file.

*If* you could run CiderPress, or open the file in an emulator, you
could save it as a .shk file.
Isn't connectivity fun? ;-)

It is possible that due to the fact that you're using an http file
host, the corruption you're experiencing isn't due to the fact that
you're not compressing the file, but is rather a byproduct of
uploading a file whose type isn't recognized, and is thus by default
assumed to be text, triggering some unwanted "line terminator"
conversions during the upload process. If that's the case, you may
find that simply renaming your file to add a .zip suffix prior to
uploading it will be enough to cause the upload to be done as binary
with no conversions. After downloading the file to the Mac, you
should be able to simply rename the file again to remove the
bogus .zip suffix and if that's the cause of the problem, the file
should be usable. It might be worth a try.

Yes my Performa 475 has a superdisk floppy drive. But NONE of my other
computers (excluding my IIgs) have a 3.5" drive in them.
that's why i have to use a http file host to transfer files from my
Windows PC to my 68k Mac, or just download them with the Mac from the
site i want to get the file from (if i don't have to convert them like
i do with a 2mf disk image). It could be the browsers causing the
issue as well.
I have a bunch of .dsk (resulting from ciderpress conversions, or
downloading from a FTP) files on my Mac that i cant seem to get
anything to see. maybe if i use PRoDOSifier to try to fix the
filetype they might work but i do not know what filetype to set for a
.dsk.
IS there a list of file extensions and what filetype they should be
set to around on the net.

the renaming the file could work, that is what i was figuring was
happening with uploading it to a filehost. i would use ADP Pro if i
had the money to buy the cables and the USB adapter, but i dont at
the minute.
Shrinkit didn't want to do anything with the sdk or SHK files if i
didn't fix the filetype, it would show a error.
so far i did find a few programs stored in a shk and sdk formats so at
least i have something to run right now. the one game i really wanted
Dungeon Master i found in a shk format and made a disk with that.
i am getting better working with ciderpress i now can move files into
a created 2mg file. if the extension renaming works i will be able to
get them to work.
its been crazy learning how to work the IIgs and its files. but i
still have allot to learn. I am now balled from all the hair pulling
on getting everything working. but it is fun at the same time
learning about it.

Didn't Antoine just release a utility for mounting .dsk files on
a IIgs?

Use 8-bit (ProDOS) ShrinkIt--it will happily open any file type as
an archive (if it actually is one). Open Apple (Command)-S will
(S)how all files for selection.
As long as you are unShrinking disk images, you don't have to worry
about resource fork handling--the disks created will be exactly as
they were shrunk, regardless of OS.
