that's a quite reasonable analogy Willum, as you put it specifically for writing a program. As long as people don't get the impression that the 2600 is XP to the 7000s 98 overall which would be wildly inaccurate

The EMC case is because of the compression introduced on the 6000, and that is why the conversions are stuck at 5000 format. When the 6000 came out I gave Klauss information to enable reverse engineering the 6000 compression, but this was a very difficult job. Perhaps with the demise of Technics instruments any possible contractual reasons may allow a rethink, we shall have to see whether it's worth his while now.
