Congratulations!
Now you can have fun like in the old days.
I am glad that the Opus Discovery clone will be used and will bring satisfaction to its owner.
Have fun :)

Dear friends,
my Opus clone is working fine and I can read again almost all the old important discs I had.

At this point I would like to be able to copy them on .OPD images to keep them safe and be able to use on some emulator.
So in addition to the original 180K drive, I also connected a Gotek drive with FlashFloppy firmware. On Gotek I put a pendrive with some blank images created with an emulator.

I thought a flat cable with two connectors and a correct AB / BA jumper setting was sufficient.
In reality I have not found a working configuration with which to access the contents of the different discs.
So I tried different combination of S0 and S1 pin drives. And some for AB/BA.... Nothing

At last I used a flat cable for PC (that is a classic flat cable with the 5 inverted wires on the first connector) and with the configuration drawn in the diagram that I attach, I can read the contents of the different discs.
So I loaded the Disc Manger program to copy the files from the real disc (disc 1) to Gotek (disc 2), but when copying, when it accesses disc 2 it gives me the error "E write protected".

I tried to understand if this error was due to the empty image I had created or to the pendrive that contains it (I remember that unit 2 is a Gotek).
If I connect the Gotek, as the only disc, I can write inside the image without any problem.
Am I doing something wrong?

I seem to remember that Zaxon made a setup similar to mine with a real drive and Gotek and it seems to work.
Can you confirm the type of flat cable to use and the S0 / S1 settings on the individual drives?

Please, can you help me?
Thank you

Claudio

Dear friends,
I answer myself :-)

To connect two drives you need:
- A straight flat cable: those for PCs don't work.
- One drive must be set as S0 (drive 1) and the other as S1 (drive 2).
- By changing the orientation of the AB / BA jumpers, drive 1 can be swapped with 2 and vice versa.

So I solved it and now it starts to recover the old disks, making .OPD images

Thanks again

Claudio

Dicesare, I don't understand. That configuration (not PC-flat cable, S0-S1 pin drives, AB/BA jumper ) work correctly or not?
I want connect FlashFloppy Gotek to Opus so your trials are helpful.

I found program to write .opd images to floppy disks on PC:

Dear R-Type

My last configuration (that of August 20) was full working, I summarize for a clarity

- Straight data cable for both drives (no cross wires)
- My setup have drive 1 as Gotek (S0 set on this drive) and drive 2 as original 180k Opus drive (S1 set on this drive)
- AB/BA jumper set horizontal as to the edge connector. If you need to swap drive 1 with drive 2 set the jumper vertical as to the edge connector.

Thanks I already knew it.
I'm dumping my old 180k floppy I used years ago, I was working with patience and IPA (to wash floppy surface)!

If you need some other info, ask me!
Good luck!
