Original thread and symptoms: Requieum for a Q605, repair or . . .

Interesting, you're already doing the Pizza Box toggle switch method for getting the Video Circuitry fired up without a battery in the second instance: Boot chimes, pause, four rising notes, pause, then four falling notes. I hadn't noted any differences in the tempo of the death chimes due to battery state, hrmmm? I remember my notes on the FDD Cage saying VRAM was required, I wonder if just one SIMM from your LC is enough though, does it need a pair? One of my LC VRAM SIMMs actually says something like "For LC Use only."

BTW, you forgot to mention that you were expecting to receive something I cobbled together for you using that guaranteed non-working MoBo in the nicer of my pair of 475 cases. ;)
