I haven't used it | extensively for writing, but I did find that Bank Street Writer | II will not format or write to a DSK image properly. | | I'm really impressed w/ the FloppyEmu. The creator added WOZ | disk image support fairly recently and I threw him some extra | cash when I downloaded the new firmware, to show my | appreciation for his continued development on the device. | dekhn wrote: | It's really quite amazing what a hobbyist can make these days | (and sell on the internet). | | I would prefer a device that supported network storage, so I | could just point it at my server which has thousands of disk | images. | bdowling wrote: | > I would prefer a device that supported network storage | | You may be able to do this using a Wi-Fi enabled SD card | with a floppy emulator. | snvzz wrote: | There's been a lot of open hardware floppy controller projects | lately.

Mostly it does come down to capture cards... if you | can, use an SVHS Stereo of higher quality for the player, and | svhs input... you'll get slightly higher quality. | | Though it's been well over a decade since I've touched/used | anything like this. I do have a friend that does some | conversions as a business... he uses pro grade svhs player and | it's slightly better quality, but far from ideal. | | Similar for old super-8 videos, mostly comes down to playing | and recording via webcam in a controlled environment. If you go | completely black, the recording washes out, so want some light | in the playback/recording, and then runs through some filters. | reaperducer wrote: | I see that it's been tested up to MacOS Sierra.

Even though the cable fits, the | BIOS does not recognize it. | forinti wrote: | AFAIK, the cables were identical in 3.5" and 5.25" drives. | | So this interface probably works for both. | | I swapped out a 5.25" drive on a BBC Micro for a modern 3.5" | drive and even got it to work using HD media (the BBC used SD). | kristopolous wrote: | They were.

I bet there's a good | arbitrage on eBay here if I'm right. | | There's systems that go the other way, sd card/usb disk to fake | floppy but what I really want is usb to fake floppy. In this | model the usb exposes itself as a configurable given capacity | drive on both ends of the pipe, fake on both ends | | At the modern computer I copy over the files to the fake drive | disk by disk and on the old computer I tap enter accordingly. | Then someone can do a 20 disk install or whatever without a | bunch of effort.

I still haven't gotten that to work. | | Current Win10 install _kinda_ works, but the best success I | 've had is with an old 32-bit installation of WinXP. Even | then, doing the things you'd like to do with a floppy drive | (reading reliably, reading when inserted, decoupling the | unmount/eject ((as opposed to the old way Mac handled it))) | mechanism is difficult. Also, some USB->ATAPI bridges simply | don't work with ATAPI floppy devices. | | If you've ever wanted to solve a problem that no one else has | attempted (because no one cares, at all) there's a project | for you. | tracker1 wrote: | I did get a USB floppy drive a few years ago... don't even | know for sure if/where I have it as I never actually used | it... got it just in case I needed to get some data off for | friends/family, but that use case never presented itself... | I'd moved off of all floppy media by 2001. | | It's wild when I hear/read about production systems still | running with old floppy media. | NegativeLatency wrote: | I think this might be a better fit for archiving software? | snvzz wrote: | >USB FDD | | Is grossly insufficient, unfortunately.
