Started to test the Z80 Application Board (APB) + Studio 68. In this test the RAM is inside the FPGA and preloaded with a Z80 HALT instruction (the 68SEC000 CPU on the Studio 68 is held in high-Z). The Studio 68 here acts as slave to the Z80 APB.

The "Z80 Application Board" (APB) PCB is just arrived...😀 Thanks to PCBWay that kindly offered me to do this beautiful 4-layer PCB! The Z80 APB allows to connect a Z80 to the Studio 68 board, so it is possible to make "experiments" with custom I/O synthesized inside the FPGA...
