[comp.sys.atari.st] Question: Indus GTS 100 compat. w. Spectre 128

leo@emerald.jpl.nasa.gov (03/10/90)

I am a Spectre 128 owner thinking about buying an 
Indus GTS 100(X) drive.  Are there any problems using
this drive with Spectre?

  I also was interested in getting the GTS-100, but thought I had heard
  that it didn't work with Spectre. However, just last night I happened
  to read an article by Dave Small in ST World, titled "When Networks
  Collide or: GEnie meets Usenet", where he states (under 'Gadgets Rumours
  & Innuendo'):

     There's a Future Systems (everyone says "Indus") GTS-100 drive
     here that now works with GCR. This is the only brand of drive that
     gave GCR trouble; five minutes with a soldering iron fixes it. This
     hasn't been done before. We've posted instructions. More on this later.

The Indus GTS uses an NEC mechanism that tends to filter out Mac data on
the innermost 16 tracks (so , first off, most of the disks should be
readable to begin with).

	This can be cured by shorting inductor L7 and adding a capacitor
to change the frequency of the filter to include GCR data.

	Complete instructions can be posted (or emailed) upon request; let
me know. It's around 5 minutes of soldering and 50 cents of capacitor in
parts.

	I've been told that "Indus" (okay, it's Future Systems) has switched to
a new NEC mechanism that we'll also have to figure out. (what fun). Anywho,
the above applies, I believe, to the 1035 mech; don't try it on an 1037.
