I'm a bit surprised that there don't seem to be any adaptations that hook into the head pre-amps and use an ADC to give a view of what the read signal actually looks like. Maybe that's asking too much--there are certainly MCUs with sufficiently fast ADCs and memory to do this. --Chuck

I would have liked to find that comparison site earlier. However I think I'd still have gone for greaseweazle. On Sun, 11 Jun 2023, 09:29 Tony Duell via cctalk, wrote: > Well, I've got the Greaseweazle software to run, but I don't know why, > which is hardly encouraging. > > Installing various

Sorry to drip-feed this, but https://wiki.archiveteam.org/index.php/Rescuing_Floppy_Disks is a useful source on comparing various methods. It's clear that this type of interface has particularly strong support on Apple due to their previous use of non-IBM formats, and Amiga is also quite common (I

Further on the greaseweazle docs - there is a forum at https://github.com/keirf/greaseweazle/discussions which seems quite lively and may be the right place to start. On Sun, Jun 11, 2023 at 9:56 AM Adrian Godwin wrote: > On Sun, Jun 11, 2023 at 9:29 AM Tony Duell via cctalk < >

Well, I've got the Greaseweazle software to run, but I don't know why, which is hardly encouraging. Installing various Windows updates, downloading .dlls, and puting the latter in various directories changed the error messages but it never actually worked. But downloading the latest Greaseweazle
