I would create around 10 to 15 minuets of audio and then back it up on to a pile of floppy's as a multi disk zip then remove the original files and start on the next 10 to 15 minutes. If you have not tried using floppy's for storing audio then DON'T! You can get about 90 seconds per disk
I eventually got a machine with a 40 Gig hard drive and assembled the 8 hour piece from the 300 plus floppy disks into 8 or 9 files and it was about 12 minutes to long as this was 2 or 3 days work I just could not bring myself to edit that much out – now remember I had been working on this for a couple of years and I'm not the most mentally stable person at the best of times – so my solution – make it a 24 hour long piece!
And I made bloody sure that when the 24 hour piece was assembled it was 24 hours :-} I have tried to give the sounds the same type of texture that you get visualy with acid. I like the way repeated words can morph into another word - there is a section of Gisberg saying LSD which begins very slow and speeds up - about a third of the way in I hear iot as "halo paul" for a while before it changes again.
