Great stuff Gunnar, everything seem to be OK with the exception of a small gap toward the end of the 'DIS--1' sequence, but it doesn't really matter. I loaded them into my KN6000 and then resaved them back to floppy. The compression used in the KN6000 filing sytem, certainly seems to be very efficient. The 10 files which you converted took up 1.76 Mb whereas after conversion by the KN6000 filing system, the volume was reduced to 226 Kb. I suppose that such a difference may also have been partially due to the KN1000 to KN5000 conversion process.
Thank you very much for your time and effort - it really is appreciated
