Can it do that or only 880k ?

I have one of these drives in an A2000 and it works just as well as the real deal in both of my A4000D's. No problem with PC 1.44 or Amiga 1.76

wow, that looks interesting, wish there was a place to buy them at not too high price, or even better hard/hack on aminet  that works similar.

I had bought an external high density disk drive for my CD32.  Worked like a charm.  It's in my basement somewhere along with my CD32, SX-1 and a ton of awesome CD32 creme of the crop CD32 games that I haven't found and sold on eBay yet...  I thought my drive was a CHINON...or am I getting confused with another component?

Hi:
why do you have the cd32 and sx1 standing there. You could just sell it to me, i will treat it gently. As my whole amiga collection.
Best Regards

Rod :-D

I have read in an old french amiga review that amiga HD drives are very sensitive to magnetic fiels, even when mounted in a proper tower.
Personnaly i use a catweasel in my A1200T and i can read/write perfectly and fast 1,44MB MSDOS and 1,76MB FFS, and even a special amiga format called Catweasl Extra of 2,38MB.
Floppies are not so useful these days but a catweasel can be handy.

On that site it mentions a small pcb adapter.... that wouldn't be the amiga technologies adapter for using crappy PC floppies in the newer a1200s would it?  I've got one of those sitting around somewhere, and there are some of those nice sony drives on ebay BIN for £2 as I write.


 Ohhh, I see.  It's that red PCB attached to the back of the floppy.   Ohh well.  Back to being a space-filler, crappy amiga tech PCB thingy.

880k for DF0: is pretty ropey today for an A1200 desktop's internal drive. I still think floppies have their use even with the plethora of USB memory pens etc. out there but it would be great for some company to offer an all-in-one upgrade drive so we can read/write 1.44MB MS-DOS format.

Why did they give the A1200 an 880K drive anyway when the A4000 got a 1.76MB high-density. They were both darn expensive AGA machines...

The hardware hack I've read is far too complicated for the average user to contemplate - it involves snapping, bending, soldering and crossing your fingers; not to mention finding the particular drive this hack works exclusively on!

There appear to be 2 versions of the Chinon 357A
1,76MB floppy drive: The "normal" A4000 one,
and the "flat" version. I have installed the flat
Chinon 1,76MB drive in my A600. Works perfect!
Should also be working with an A1200, but because
I don't own an A1200(not anymore), I'm not sure.

2 words.. cost cutting.
The same reason they didn't include any fast ram that would have doubled performance on the A1200.. or an FPU (even though the motherboard was designed to take one),or a battery backed clock(ditto), or a hard drive as standard.
 They even cut out 2 resistors, a transistor and an LED that would have given a PCMCIA activity light just to save a few pennies.

That was a subtle hint that it's all for sale but just haven't gotten around to it yet.  By the way, shipping to Chile would cost a pretty bib penny.

Quite, I seem to remember from an article in some British mag that C= said that it was either 2MB chipmem standard or a HD diskdrive. So C= chose for more RAM.

The DD drive in A1200 is probably the reason why games continued to be produced on DD disks instead of HD. Not that it matters much nowadays (thanks WHDLoad!), but back then we've had more disk swapping as the result. :-D

Yup.

FB-357A: Tall drive (later A3000s, early A4000s)

FZ-357A: Normal ('slim') size drive (later A4000s)

What? C= made a sensible decision? Where's the 'faints in suprise' smiley when you need one ..
 I remember the original idea was for a 1MB A1200 with the option for another 1MB upgrade in what is now the clockport header, but I didn't know they were thinking of a HD floppy though.
