Hmm, OK, I'll bite - what disk do you have?

Some random title about "your perfect shape" - something to do with women's clothing, and finding fashions that best fit particular body styles. It's probably a simple DOS hack, and I'll be able to find a Computist technique (probably COPYA with the "make-DOS-not-care" pokes) that will do the job.

But that's not even the point. Not every system has a HotRod and LoGo to crack everything in sight. Sometimes we come across disks from computer systems that don't have anyone around that remembers anything any more. I worked with a couple of universities to read and reconstruct some disks from a BTOS/CTOS system - they used Kryoflux, who would speak to them because they were educational institutions, and I wrote and donated my own decoding software back to Device Side for the FC5025 who is a little more open (source) minded.

So these "read the flux transitions" devices are useful for lots of situations where the original controller isn't around any more, and you still need to tease out the bits.
