Me and a friend are doing an Amiga 500 trapdoor expansion card that has an FPGA, an SRAM, and a Raspberry Pi 3 on it. The memory in the SRAM is shared between the A500 and the Raspberry. The A500 "sees" a DRAM interface and the Raspberry communicates with the FPGA via SPI. While prototyping we are using a DE10-Lite card (https://www.altera.com/solutions/par...ite-board.html). It is up and running and both sides (A500 and RPi) can read and write to the shared memory simultaneously. Next steps are adding a real-time clock and then making a proper PCB. We will release the design once it's complete.
