PC (Piece-O-Chit) Floppies

[z36ra]

Anyone have ideas on how to get PC floppies working on Amiga.

I found a couple of websites that say you can do it but none that say how.

What I've found is that part of the problem is getting a drive with jumpers so you can set RY (disk Ready) on pin 34 of the floppy cable. I have had success getting drives to work when I boot with a disk in the drive but getting the Amiga to see that I have changed disks or that there is no disk in the drive is the next problem. I have also had some success when setting the drive ID to 0 (DS0).

It sure would be nice to have a nice new fresh drive in my Amigas, even if I had to use a 1.44M drive as a 880K.

How much is catweasle compared to a PC floppy drive?

are you talking about the drives or the disks?

one thing i know for sure is that my A4000T came with an ordinary High Density Panasonic FDD

My 1200 also has a Panasonic (Matsushita)... That may be pronounced differently depending on your local.

I'm not familiar with the 4000 but my 1200 has a low density drive. Which brings up my next point. Some drives have a jumper to select density. I have a drive that allows this but documentation on the jumper settings is foggy at best.

I think what you need is a Kylwalda.

"Allows to use standard PC Floppy drives as replacement of DF0."

You can get it from Power Computing but there's probably somewhere nearer you that can supply it to you.

The Kylwalda is only £19.95, compared to the Catweasel's £79.95.  The Catweasel also needs a zorro busboard for the A1200.

I don't really know about this so someone will probably correct me.  Hope that helps tho :-)

same drive. it works at 880k on my A4000T

you might find some instructions on aminet

ive found hardware hacks for FDD's on aminet before
but i dont know how good they are
or whats required

I forgot to check Amiga-Hardware.

Here's a link straight to the Kylwalda

Ah there is a clock-port version of Catweasel Mk II.

Eyetech used to sell an interface to connect a standard pc floppy drive . :-)

I know you've got this link last night z36ra, but I thought I'd put them here incase anybody else missed it on Aminet.

I've not tested this but I've been told that it work. If you have a Sony HD drive you can switch pin 2 and 34 on the cable and the drive should then work as an ordinary DD drive in the Amiga with disk clicking and auto checking and everything.

Again I've not tried this yet but will when I need a new drive, cause a floppycable isn't as expencive as some of these "floppy controllers" out there. ;-)

I searched my drives and found an old Sony MPF420-1 and got it to work. I will post the information to my website. The trick was to set the drive number to 0 and then add a jumper to get disk checking to work.

Good to see you got it working.  A lot cheaper than a floppy controller aswell :-)

I slapped this together in a hurry. This is definately a hack as I had no clue what I was doing until I finally got it to work.

I got another one working today.
I will prepare the instruction on my website and have it up tonight sometime.

It's a Teac FD-235HF-3823. The jumper setting will be the same for any FD-235HF-38xx series.
