IBM PC (clone/compatible) floppy drives which WORKED in my Amigas

[da9000]

@nyder:

What I wrote (initially) is for getting an "880KB" drive into your Amiga, by using a PC high density drive. I've not managed to get a PC high density drive to behave as an Amiga high density drive. Not yet.

What delshay is using is an elecronic card (red in color and it seems to come with certain tower conversion kits, I think those from Elbox), which will allow said PC high density drives to ALSO be used as Amiga high density drives (1760KB). He's also talking about having found a floppy drive that contains also a built-in flash memory card reader, and said drive can be used with Amigas without a "RDY line diode hack", of which I've not heard.

There's also the "Catweasel" solution for both PCs and Amigas. Search for it on www.amiga-hardware.com or amiga.resource.cx elsewhere.

Hope this all makes sense? If not, ask away

@da9000

im not useing the interface,iv open up the floppy drive & re-wired the drive it-self.

as for the RDY sig theres soldering pad on the main floppy drive cct board which gos to the controller chip & it works perfect..


all iv left to do is getting the drive to work in HD mode..

the floppy drive im talking about has the floppy on the bottom & card reader above..


** do not get the one with floppy drive above the card reader do at your own risk..

the drive with the floppy on the bottom has a few soldering pads a few options to config it.

if u fit this drive in a A1200D u have to glue two nuts on the inner side of the drive **before** puttiing it back togeter..


***** all mods at your own risk ***

Mitsumi - D359T6 and T5 needs soldering but works great.
We are collecting some infos too:

iv read somewhere i forgot which website,that the RDY sig is on almost every drive,its just not marked on some drives..

@Chain:

could you please translate the important stuff from that site? I'm curious to know, but no Czech reading ability here

Thanks

Any info on Epson SMD-1300?

Exactly what kind of testing have you done with those drives?
It's one thing to see a disk icon on Workbench, but have you tried opening a copy program and copying from a known working drive to the modded drive?  Copy back the other way again?  Formatting and filling the disk up?
Booting from a NDOS game floppy disk?

I have played about with lots of drives, and whilst I found lots that looked like they worked, after heavy testing I found some drives didn't really work exactly like an Amiga floppy drive should.

With the pin 2 <---> 34 swap in place, and the diode from DF1's Pin 1 RDY signal to (Pin 10?) on the cable, you can get a lot of drives to function.  But only a few really fully work.
I was fiddling with one the other day, I could copy and delete files, I could insert disk see an icon and watch it disappear when I removed the disk and I could format, but if I opened a program like Xcopy, it would tell me that there was no disk in the drive.  Wouldn't matter what I did.

A better solution I believe is this...

look at amega.jpg and amega2.jpg.

I havn't tried yet myself, but I'm going to soon.

Xcopy (and NDOS) didnt work because of RDY, check the diode..
..or make a real READY signal using simple boards from aminet/hard/hack

Thanks alot for the link and list. Gonna print out that so i know what to look for the next time i dig a bit at my electronic recycling center
