Reid, I have a QS6 that's doing the same exact thing. Could you please e-mail me and correspond? This gives me hope that it's saveable. I'm also a tech (with 30 years of experience.) I'm Narfman96 at yahoo dot com. I'm also the owner of the Alesis QS Synthesizer Yahoo group.

: Hi, Ben. Thanks for answering.

: I've discovered one broken address trace on the bus, and one other open pin on one of the chips. I'll try soldering jumper wires on those and see what that does. One other surprising thing I found (the hard way) is that the 7805 regulator's heatsink gets painfully hot, but I've been informed by a former Alesis employee who worked on this unit that that's normal. Sure enough, the datasheet says its rated for up to 125C, and it feels like it's damned near boiling! I didn't try a spit-test. :)
: BTW, I've seen your great web page, and I'm going to try programming a couple of cheap flash cards I picked up on ebay. I got one for less that $7 US, with free shipping! I'll report my results.

: Thanks again.

: Reid
