disktool software, ifs tape generation

Hello,

I would like to add a non Symbolics disk i.e. not supported mfm disk
via 'disk type' in the fep to my 3640 machine.
What I learnt is that I would need the 'disktool' software for Genera.
This problem might have come already to others so I hope that someone
still might have a copy of it.

I'm as well interesting in the lisp code for generating a so called
'breath-of-live tape'. By browsing older netnews articles I found a
posting concerning the code to generate that tape.
Here's the link to the posting:

Does someone still have that code ?

Any bit of information will be appreciated.

Regards,

Marc Holz
