Hi. I have recently acquired a Lynx 470, with manual and cables. It's in really good shape; the only problem is that it doesn't work. All the LEDs light up in test mode (I replaced the barely visible red ones with high efficiency ones, and a larger resistor to dim them a bit). The whole thing seems to have been hand-soldered, and was not cleaned of flux afterward.
Going through the test sequence in the manual, it won't make the drive seek. I found a bad 74LS85 comparator (first chip I looked at) but the other chips _appear_ to be working OK.
It would be a lot easier to troubleshoot this thing if I had a schematic. Does anyone know where I could find one?
Thanks,
Steve
