Yeah, I’d check the oscillator and then start swapping out chips if they are socketed.

When I turn on the coco, it displays the Disk Basic copyright, the Coconet version and hangs on the MicroSD Pak detection. I opened the cartridge and saw no apparent damage. I tried reseating the socketed chips to no avail. I suspect the uDrive module to be the problem. The power on led doesn't go on when I turn on the coco.
