I used my hot air rework tool to remove the parts that were to be salvaged from the old board. These were still part of the design of the new board. For each, I removed it carefully and then soldered the part onto the new board.
This included the gold pins that form the connector that the IBM 1130 cables are plugged onto. For this, I used the soldering iron and pushed the pin up a bit so that I could then grip it with pliers and remove it while heating again. I use a spare socket to push the pins into, ensuring the 24 pins are aligned properly when I solder them down to the new board.
I examined the board closely with the microscope, pushed on leads to ensure a good bond for each pin to its pad, and did a few continuity tests including validating there was no short on the main power rails on the board.
I had to return home to wait for a delivery (an area rug was cleaned by an outside service), but will attach and test on the 1130 system when I get back to the shop.
