Interesting video.
Quite often the easiest way to get data from old disks however is not via the original computer, but via Greaseweazel. It's also the safest way since you can have better control over the hardware.
You read the flux in, convert it to binary data, and then you just pull the files straight from the image after you save it.
I've been doing that with an "only copy" of a 63 chapter novel someone lost back in the 80s. Once I had the data, it's just a matter of reading the directory structure and pulling the raw wordstar data straight from the disk. Since wordstar is a fairly easy to convert format, I can convert that straight back to text.
Most importantly, old disks are prone to shredding, so it also allows me to coat the disk with cyclomethicone before I start to protect them for a half hour or so while I recover the data.
The end result is that I can usually get the data from them far more reliably than the old computers can read a raw disk ( though cyclomethicone can also be used for that too ).
