#ZoomFloppy
Sunday afternoon black magic. Writing a D64 disk image to a physical floppy disk using a ZoomFloppy board and a RaspberryPi. #Commodore64

I bought a ZoomFloppy and hooked it up to my laptop and one of my existing Commodore floppy drives.
Not the most intuitive experience, but I managed to plough through the instructions and finally get it to back up the disks to D64 files that would work with Vice.

I'm dumping some more #C64 disks with my #zoomfloppy and it's a bit of a process with many cables. So far so good though.

Thanks! I didn't knew about that device. store.go4retro.com/zoomfloppy/

I've started researching tools and techniques for dumping old disks, primarily #C64 disks, but potentially other formats too. I've read about several methods and devices, including the XX1541 cables, ZoomFloppy, KryoFlux, SuperCard Pro, Greaseweazle, and the Ultimate-II cartridge. 🧵

My ZoomFloppy arrived. I'll try using it tomorrow to save what's on my dying Commodore 64 floppy disks.

I use this little XUM1541 device together with

OpenCBM: github.com/OpenCBM/Open...
and D64EIC blog.worldofjani.com?p=647 to combine D64 images when the XUM can't get a single stable one.

As far as I know XUM1541 can't really do anything sophisticated, KryoFlux or ZoomFloppy are better for that.

Thanks! Right, the ZoomFloppy seems to be preferred over the XUM1541. The ZoomFloppy is shipped from the US, which is slow and adds import costs. The XUM1541 is easier to get here in the Netherlands though, it seems. I don't mind it being slower, I just need to transfer ~50 disks.

TODAY I kept up with the Commodore!

I got a pi1541 disk emulator so I can run those crazy european PAL demos on my 1983 NA C64 with a Vic II kawari small board.
It was getting old writing to real floppies with a ZoomFloppy board.

For unprotected CBMDOS disks, XUM1541 / ZoomFloppy with OpenCBM is a good solution. Assume this is what you have. If you have an Ultimate64 or 1541-Ultimate cart, you can just hook up the drive and transfer directly. But that's too easy to be any fun at all. 😀

I'm sure I have used my Action Replay V6 cartridge (or an image of the same cartridge with Kung Fu Flash) for this, and it works.

I would normally use an XUM1541 interface (ZoomFloppy clone) with OpenCBM for this purpose though.

No worries! If you want to DM me an email address I can send you the files. I backed them up using a ZoomFloppy and they all seemed to transfer error free but obviously they will need testing and checking to ensure everything works.

Long weekends were meant for projects.

And I have good news and bad news on the C64 side.

I was able to install ZoomFloppy and the CBMX stuff.

However, I've discovered that my two 1541 drives are both faulty in different ways. So away goes this project, but at least there are troubleshoot vids.

C64 fans, I tried getting this 4-disk demo ('Mojo' from this year's X2023) https://csdb.dk/release/?id=232966 to my old breadbin NTSC C64, to no avail. It seems it's in 40-track d64 format. First, I tried ZoomFloppy, then, run it in a BackBit. It is not liked! Any ideas?

thanks for the reply! So I'm aiming to use my real 1541c, but I have to dig into the opencbm documentation to make sure I can address sectors beyond #35 so I can write from my PC using my ZoomFloppy I bought ages ago. I also have to wait for a VIC-II Kawari to arrive from Ireland to run PAL things..

May I suggest 64Copy and a Zoom.. I think it's called Zoomfloppy?

If you have a CMD FD-2000 or FD-4000 drive that constantly has data being updated and added to it what do you find is the best and easiest way to back it up on the regular? ZoomFloppy, using U64/C64U VR drives?
Would love to hear your input on this!

My ZoomFloppy is working well at dumping my Commodore 64 disks but my 1541-II drive gets tired after a few disks and won’t read any more. I think the drive is on its death bed.

Unfortunately not, the device connects to the C64 - but you can create a network connection between it and a PC/Macbook to send files I believe. For connecting a 1541-II, something like a Greaseweazle or ZoomFloppy device would do the trick - though not sure if they work with Mac devices.
