From the project
MSX Goa'uld board with Xilinx XC7A35T
MSX2+ engine in Z80 socket. It turns one MSX into an MSX2+ by replacing Z80 processor. FPGA in board contains: Z80 V9958 with hdmi output MSX2+ BIOS 4MB mapper RTC PSG through hdmi SCC (audio only) through hdmi OPLL through hdmi * SD card interface with Nextor
Place SCC cartridges in slot 1 to get SCC sound through HDMI
Revision 2 uses SOIC-20, TSSOP-20 for 74LS245 and 74LVC245 ICs, which are smaller:
