How to make disks for a IIGS?

Recommended Posts

I recently acquired a complete IIGS, which will be arriving in the mail tomorrow. The only thing is...I don't know how to make disks for it. I have beige Macs that can write 800k disks, but can classic Mac OS write IIGS disk images directly or do I need a special program to do it?

Yeah, ProDOS file system is the format you're looking for, and the IIgs can definitely boot off of a high density floppy disk. ProDOS only accepts a max size of 32 MB IIRC, but that should be fine unless you're really thinking of pushing the limits of your IIgs.

 

IIgs System 6 and I believe 5 also have an HFS translator, though it has been known to have a data loss bug. This was allegedly fixed in one of the unofficial, fan driven System 6 updates (6.0.3? 6.0.4?) but I remember that being an issue with owning a IIgs for a long, long time.

was a bit confused with Apple DOS 3.3, ProDOS is correct.

The IIgs has 800K floppy drives and will not read 1.44mb disks without a special expensive 3rd party drive.

 

If you mean you can format a 1.44mb floppy as 800K well then they are not reliable when done like that.

 

Apples website has (or used to anyway) disk images for GS/OS 6.01 that you can dump to disk using a 68K mac easily enough. You will need a couple MB of RAM to run this.

 

Most utilities were compressed using a GS/OS app called Shrinkwrap GS, files have a .shk filename.

 

If you have a working HD and install GS/OS on it life is simple, you can make a mac partition on the drive and just dump the files over using a serial cable and a 68K mac.

I'm going to try to find an older version like GS/OS 4 or 5, just something to boot the system. I don't have a drive to install GS/OS to sadly.

 

I found a download of GS/OS 4.02 but the individual disks just show up as plain files and seem to be slightly too big to fit on an 800k disk...

I need to get my SCSI + HD running again and dump some disk images. I have the TOSEC IIgs archive from about 10 years ago on my server which I also have to fix the boot drive. I will probably connect a bernouli drive to the  IIgs and another to one of my IIfx to make transfers easier.

 

If you have early 68K Mac without superdrives, Atari ST, Amiga, or Apple IIgs systems I suggest stocking up on 800K disks while you still can. Old Avery floppy disk labels for laser printers are nice as well.

I actually bought 10 720k disks recently entirely because I was getting this IIGS and knew I'd need software. Well okay, I also have a Tandy 1000SX with a 720k drive and figured some 80s DOS games on 720k disks might be a good idea.

Ten are not that many disks. When I first got into Amigas I bulk purchased 500 new DD disks, got 500 360K 5.25" DD when I got my C64 again. No idea how many 1.44MB disks I have purchased in bulk during my lifetime. You can probably just buy a Gotek floppy emulator and flash disk to save on clutter but I go old school.

Jeez, 500 disks! Based on my getting 10 720k disks for 5 bucks, 500 disks would be...a lot! And yeah, I was honestly just going to Gotek both of my Amigas anyway.

I kick myself for only buying 500 when they were $30 or something shipped. Duplication grade blowout sale. Still have at least half I think.

 

Gotek are great for booters for use on something like an A500, but for HD installable games I like real disks (and a Gotek for each Amiga gets expensive). I have a whole shelf of boxed Amiga games anyway.

 

This hobby is a money pit.

Oh yeah, I put a CF card HD in my A1200 already. Still haven't really worked out how you put stuff on it.

 

At least a CF card for an A1200 is like 25 dollars or something and readily available, unlike the CFFA3000 or whatever it's called that costs like 200 dollars and only 12 get made at a time or something.

I have stacks of 40GB IDE laptop drives for my A1200 is needed. The 1200 takes (supported) PCMCIA ethernet cards and some wireless WEP cards as well so moving files is not that bad. You just need the 3rd party software/drivers to get things working (and time to read directions). Its been a decade or more since I set up my 1200 and probably forgot how to do it.

 

Lookup English Amiga Board (EAB) forum, lots of help there.

Thanks, that's some good advice.

 

I guess for now I'll take these GS/OS files over to a Mac to see if it can recognize them. I really need a system with a SCSI2SD where I can just pop off the top or side to get the SD card out...

Ah yes, I almost forgot the Floppy Emu. I was going to go SCSI card and SCSI2SD myself but a Floppy Emu would be cheaper, since that's like...$120? for the whole thing.

Hey, just here because I'm having kinda the same problem, I don't know how to write an IIGS disk, because I really want to use GS/OS. I've heard that I should get an image and put it through Disk Copy, but for some reason, the computer I was doing it on was being fussy and didn't want to put the image on the hard drive (I put it on a floppy disk from a pc, so I might've done something wrong) nor did it want to even load it into Disk Copy, It would just spit out the disk and ask me to insert it, but when I did, it would do that same thing, and I would eventually have to force shut down (unplug it). I might try it on another computer, but I'm too lazy rn. I've been told that I should load an Apple IIGS emulator and do something with that, maybe it'll read the floppy drive and I can just copy the sys folder onto it I don't know. But, if it wouldn't work with disk copy, I don't feel like going through all that effort of having to put files onto a floppy, or maybe a cd and transfer it if it's not gonna work. Maybe if I get an IIGS CF hard drive expansion, it'll work but those are quite expensive for me. Tell me what happens and what you did.

using a PC is never a good idea in this matter.

 

You will better find a Macintosh able to fill the gap and write the disk.

My MacBook Pro was out, and I couldn't get it, so I had to use some random Windows laptop. I think I used my MacBook when I got it back. I couldn't have used the programs because the VM which I had them on is on my MacBook, and I think that the file format won't be able to write with the programs I have. I could probably use one of my early Mac OS 10 machines or maybe my iMac G3 Rev. B and transfer it via a USB stick, then transfer it to a floppy drive, then transfer that to an older mac to use disk copy.

If you have a 1.4 MB drive for the IIgs, you are golden. Otherwise, there is no USB drive in existence that will write 800ks. You will still need an old Mac.

Well yes, but if you use something like an iBook G4 you can write the files to HFS formatted floppy disks to get them to the old Mac if you have no other way.

I think I just figured it out! I just made a GS/OS boot disk!! So, I put the files onto a flash drive and then put the flash drive onto my Rev. B iMac G3 (which runs Mac OS 9.2) then put those files onto a floppy disk (via a USB floppy drive) then transfer it to a older machine, one with a floppy drive and that can format to Prodos disk (I used a Power Mac 4400/200). Then, on the older computer, you get another 1.44 floppy (preferably one you don't need) and put tape over the hole on the right side of the disk and insert it, it'll ask you if you'll wanna format it to ProDOS version. Then take the first floppy and copy the files from the first floppy and put it onto the second. That should be it!

Been struggling a lot to make a boot disk because everything I find is in .2mg format, which Disk Copy 6.3 and DiskDup+ can't do anything with. I even tried Disk Copy 4.2 and that didn't work either.

 

I know Apple had ProDOS disk images for GS/OS hosted on their site, is there a backup of those images?

 

EDIT: I tried using a program called CiderPress to convert a .2mg to a .dsk but the .dsk file isn't being recognized by Disk Copy 4.2 either.

If you have a Windows box lying around I believe CiderPress can convert .2mg to Diskcopy 4.2 format. Yes, it'd be pretty mickey-mouse to have to do that but it should work in principle. (IE, convert them on windows, copy them to the mac, go from there.)

I did use CiderPress but then I had to use ResEdit on the Mac itself to make the DiskCopy files usable. It's finally working now though!
