A4000D floppy drive - HD or DD?

[dnelsonfl]

What brand floppy drives did the 4000D ship with originally? I'm looking at a Panisonic with a large "C" and model A3050 stamped on it. It does not appear to have any jumpers or switches. Just the floppy cable connector and the power plug. I'd like to verify if it's just DD or if its HD. It recognizes DD disks, not HD disks, but the floppy cable doesn't look like it has the twist in it. Anybody come across this drive before? I imagine I could hook it up to my 3000 or to a PC to get an answer, but I'm trying to avoid disassembling more computers.

@adolescent,

Thanks for comfirming that; so only the Chinons were HD. That's what's in my 3000, I was just wondering if there was a different make in the 4000. I found more numbers under a sticker: JU-253-233P. This model is a standard 720k half-height 3.5" disc drive. Interesting that it works with the Amiga with no modifications or jumpers. Oh, well.

That means that the original HD drive was most likely replaced with the Panasonic DD drive by the original owner (assuming that you recently bought this A4000 from eBay or something).

AFAIK, some C= A1200 units came with a Panasonic drive.

Yup...my 2 A1200 that i have right now (im not not first owner tough, but i seriously doubt that previous owners made any changes)both came with Panasonic floppy drives...

Strange or common? I mean old 1200, not Amiga Technologies...

cheers

Hi,

     Right before Commodore was going to declare bankruptcy we were selling the LC'040 based machines and some of those shipped with DD floppies rather than HD ones.  Perhaps they could no longer order them - bad credit?

Again, just my 2 cents (Canadian)...

P.S.  One other thing - when you prop up the dust door on the drive, do you see white plastic sensors for the Read/write on the left and the HD sensor on the right?

dnelsonfl,
Can you re-verify the numbers, and look for a jumper block. I have a compatibility list in my Technical folder, but it refers to:

Panasonic  JU-253-033P  (with the following comments)        to make it work, set MS/MD to MD, 0/1/2/3 to 0, RY/DC to RY.

If your is a "233P", please let me know, and any jumper settings. I'll add it to my listing.

@Amiga4k,

The sticker says Panasonic. Below that are two lines with some information. The first line reads "Model   JU-253-233P" and the next line reads "C  A3050   011563". The "A3050" part is in stamped ink that's starting to rub off.

I can see where three jumper pads should be. The entire pad is covered with a black piece of maybe plastic. The black piece is in turn covered with a piece of metal across the whole pad.

From left to right, the three pads:

"0 3 2 1" , "MO SW2 MS" , "RY SW1 DC"

It does not appear as if I can change any of those, and I don't see how I can tell which setting it's set to.

It did come from a used 4000D. It's possible a previous owner kept the HD drive and threw something else in there, or maybe it came like that originally. I kinda doubt it originally came that way since it's a half-height drive and there is a bit of an empty gap when its fitted to the case.
The 4000D began life as a 4000D/30 but when it got to me, it had a 3.0 modded to rev 3.2 A3640 with 68040/25 onboard and 16MB fast ram.

Hope this information helps, and if there's anything else you want me to look at on this drive let me know.

@glitch,

Looking into the drive, I'm not seeing any white plastic sensors. But the left and right sides look identical. I googled the model number and it came up as a standard 720k floppy drive.

Thank you for looking. What your describing as (black plastic) -- is it one piece, or tiny jumpers. Just look, don't pry. No sense messing up a drive.

I'll keep the drive # on the page, making a note: not sure about the jumper settings.

[dnelsonfl]

@Amiga4k,

The black plastic is one entire piece with a metal clip over it. It does sit where the jumpers would be, according to the circuit board's printing.
