At 71, I find I must use a strong lens to inspect circuit boards for cracks and cold solder joints these days. I have the tools, after 55 years of chaseing electrons for a living, who doesn't, but trying to keep track of which hole in an 80 pin connector that I actually have the pin plugged into gets to be pretty darned tedious & mistake prone. >[1] "PC Hardware in a Nutshell" by R.B.
