daughter board XJTAG

Make a new daughter board Making a new daughter board would have allowed much more flexibility in device selection. It would also have required a decent amount of time to assemble and would have cost significantly more than any of the other options. However, it is by far the cleanest and most durable choice. Create a printed circuit board that mates with the ZIF Depending on the design of the PCB it could have been very time consuming, but would have been cheaper than using a socket converter. De-soldering and re-soldering burned-out chips would have been a slow and potentially destructive process. However, a socket could have been used on the PCB, making switching chips easy. This option would not work with high-speed devices because of design and manufacturing considerations for high-speed PCB's. There would have been almost absolute freedom in the choice of devices. This solution would not have worked with the PLCC sockets. Use a socket converter The socket converter was the fast and easy solution. The expense was still within the team's budget and was both cheaper than creating a new daughter board and less time consuming than creating a new interface.
