Ok I know some of these are old, but I just realised my webmail server was adding a graphic to the text, and as such, the mail was not going through, so here they are.
agree,silver soldering is of the highest quality for electrical connections there is, provided it is done correctly. This is true regardless of the composition of solder you use. With multiple stranded cables, there is a danger of wicking up into the insulated section, which can, but not necessarily, lead to weaknesses in the cable leading to the joint, (this is the main reason crimp connectors are recommended by many advisors, technicians and companies) however with care it can easily be avoided. The trick is, don't get too carried away with the tinning, a little goes a long way, and don't apply more heat to the joint than needed to get a nice flow. If you dally too long, the solder will wick up the strands, damaging the insulation and compromise the flexibility of the cable past the joint. Cheers.

The solder was rosin core and you used a 17watt iron. These computers flew in F-105's and just about every type of commercial airliner all around the world.We washed all solder joints with Acetone,I consider this to be ultimate quality.
