[sdiy] Broken Siel Opera 6, any ideas?

[Robert Weigel]

I believe I touch on this problem on my web at sounddoctorin.com and
follow whatever the logical links are from the global synth resource page.
But basically as I recall the problem is in the resistors and diodes and
or chip involved in the IRQ or Reset lines....maybe the DAV lines.  I
can't recall.  I'm on the road.  But I've seen this problem before.  -Bob
