This project was originally for my own private personal use, but I am deciding to make this a repository anyway. This is also my first time using vias on a PCB layout! The circuit was tested with a 74HC244 IC and TJTAG 3.0.1 and 3.0.2.1 on a few machines with success barring issues with using one 74HC244; replacing it with another 74HC244 from the same set fixed the recognition issue. This is why a 74HCT244 is recommended with this circuit. The circuit on a perfboard - prototype unit before the PCB design
