Well, there was some improvement. Now I get a startup chime every time, and it doesn't hesitate to boot. Previously I was getting equal thirds of boot, no boot, or simasimac patterns.
What has yet to improve is the SCSI. Some drives it will not detect, others it will detect but fail to initialize. I have tried the drives internally and externally. So it looks like I am going back in there tonight, especially considering that the remaining caps are in the area of the SCSI controller. I am tempted to use a hot glue gun to affix the finished caps in place, but I worry that either the heat might upset a delicate solder connection, or otherwise yield too much of a mess if I need to redo any work on parts in these areas. If replacing the rest of the caps doesn't fix the SCSI, I might desolder the controller and install a PLCC socket for whenever I locate a replacement 53c80 chip.
