It would serve me well for you to start reading from the beginning of this thread. It has already become dominated by every issue except the first question, "does anybody know of a Twin Cities prototyping shop to help solder a microcontroller board?" In about 1987 I made a wire wrapped counter board, connected by RS232, for a photomultiplier tube that counted photons measuring chemiluminescent immunoassays. Determined the reaction kinetics for "Homogeneous Ratiometric Chemiluminescent ImmunoAssays." AIDS testing was important then, and armies of lab technicians handling radioisotopes wasn't cool. Then I said to hell with it and loved raising my family. People argued when I said integrated circuits were going to greatly improve. Kind of like pushing fiber optics in 1982, "Who ever heard of glass wires?" Many years ago I liked the PCB breadboards from "Protostack," and purchased some. Their website has become very nice over the years. https://protostack.com.au/ Full specs are on their amazing web site. And the boards are beautifully masked. Their stackable breadboard PCB design easily accepts any DIP packages. I just don't have high confidence anybody can solder 100 pins in perfectly. But I can squirt a syringe into a hole.
