Re: How bout this for a gap? A disk interrupted gap.

[Terry Fritz <twftesla-at-uswest-dot-net>]

That was a long time ago before I "knew things".  The disk was some high
temp plastic and it didn't last long.  I can not say if it was better or
worse.  It didn't last long enough and I really didn't have anything to
directly compare it to at the time.

Cheers,
