.img is Disk Copy image format, should mount properly, but the format message you got confuses me.
I get such msgs with System 6, but (mostly) not with System 7.

Can you get hold of a SCSI CD ROM maybe, like the Apple CD 300?
I recall I had Office98 running with my MacII and a Daystar 68030 cpu upgrade.
4.2 may also meet your demands: http://macintoshgarden.org/apps/ms-office-42x
In case you can grab an optical SCSI, the CD images can be burned with ImgBurn on your Windows machine.
But maybe thats overkilling, as you just need some disk copy images.

I don't know, but you could try RawWrite for windows, insert a floppy disk, run RawWrite, select the image for Microsoft Word, and click write. Try inserting the floppy disk on your mac classic.

Sounds like you're doing the unstuffing of the disk image in Windows, bad idea

You're either going to need
a CD-ROMdrive for the Classic II (I had one of those), or
a physical Mac floppy disk with all the Unstuffit / Stuffit Expander software you'll need, or
a network connection on the Classic II.

What software do you already have on the Classic II ? Does it even boot yet ?

Woohoo, if you have Mac OSX with a connected floppy drive you should be in business.

So was the original file you downloaded, a .sit or a .sea ?

A .sea is a Self Extracting Archive. Stuffit (on Mac OSX and Classic Mac OS) can open these too, but they can be extracted just by running them. Almost certainly it will need Classic Mac OS, so using Mac OSX 10.5 or 10.6 may be an issue unless you do the extracting in SheepShaver ot Basilisk II.

Once you have the .img file, lock it in the Finder and use OSX Disk Utility (called Disk Copy in OSX 10.2 and earlier), you can write a perfect floppy from there. Or mount it and check the contents (may be called "Attach" in Mac OS X).
Again, OSX 10.6 might be a no-go. And you'll have to use a 1/4MB HD floppy - not the 800KB variety.

At least then you'll have a working routine, and you can then do the same with the floppy disk images from Apple ( http://support.apple.com/kb/TA48312?viewlocale=en_US ) to download and create all the floppies you need to get the Classic II up and running.

From memolry Classic II required System 7.1 or later, and the Apple site hosts only System 7.0, 7.0.1 or 7.5. The 16MHz 68030 will run 7.5 fine, but you may wish to partition the internal disk (with the Disk Tools floppy in the downloads) to allow you to also install System 7.1 - when we find it. It's just that little bit snappier (remembering from when I used both OS's on Classic II, IIsi and even IIci).

I may have a set of images for a UK System 7.1 install, alas it's somewhere between Southampton and Singapore in a shipping container. Perhaps a more thorough web search may find what you need.

So you would need some floppies to set up your system first?
Someone here might create those and send them,
if you would like to tell your address and the desired system version.
I might even do so myself, as its not a big thing to send mail to the UK.

Checking, System 7.1 was never put up by Apple, it was a paid-for upgrade. Must have been something to do with parts of it that were licenced from third parties that prevented them making it free. Much like OS8 and OS9 not being put up as free downloads by Apple.

6.0.8L was the minimum system for the Classic II so 7.0 and up is all good.

If the disk images are DiskCopy 4.2 you can write them using rawrite or dd etc but you have to strip the first 84 bytes from the image (the DC4.2 header). There are two ways to do this in the OS X terminal:

dd if=input.img of=output.img bs=1 skip=84
or
tail -c+85 input.img >output.img

If you have Snow Leopard it may be safer to do this in Windows as it could screw about with your written floppy images. There's a Windows port of dd available from here which will allow you to strip the header (you don't have to worry about the resource fork if it's a DC4.2 image).

You also have to make sure the images are 1.4mb and not 800k. This trick won't work for the latter, but then you won't be able to write 800k images on your PC anyway.

Protocol 7,

almost certainly correct about System 6.0.8L. Those were the days of long waits. I ordered my Classic II as soon as they were released (I still remember £710 with educatinal discount), but by the time I got it - more than a few months later - it was System 7.1.

Glad to hear all is well now! You can extract archives on Windows using Stuffit (I use the old Stuffit 7 as it wasn't as bloated as the newer versions). A DC4.2 image will be 1,474,644 bytes in size. Anything under 1.4mb will likely be compressed in some way (DiskCopy 6, Shrinkwrap etc) and will need to be written or converted on a Mac.

Bertyboy, I think the Classic II shipped with 7.0.1 originally, but there were delays with System 7 in the Asian market so 6.0.8L was released for three models (Classic II, LC II and Powerbook 100) to bridge the gap. I prefer it on my Classic II as I only have 4MB RAM and 7 runs a bit slow.
