CoCo Edge Buffer
Finally, a buffered Y-Cable. Feb/14/2019: Some text corrections. Update: March 16, 2019 2020/06/26: New Cable added. Starts with this PCB: Note that X1 is un-buffered, and X3 is the Y-Cable side. Then that PCB gets slightly modified and includes an overlay PCB with a isplsi2032a CPLD which acts like an MPI PAL. This cable has three IDC 40-pin card edge connectors installed. One for the SDC, one for an IDE controller, and one spare. This particular IDE controller is still in development stage. Plus these PCB's fit the small empty game boxes. That buffered PCB with the hand-wired CPLD (upside-down) and plugs into X1 on the buffer PCB. The cable does need to be "side swapped" as witnessed by the twisted pairs. When the output pins are installed on the bottom of this PCB, then no cable pair swapping is needed, just plug the Y-cable into the bottom located pins. This hand-wired PCB will be a real PC
