MSX COMPATIBLE BOARDS FOR RC2014

The MSX Compatible Boards for RC2014 project integrates classic home computer architecture with modular retro-computing hardware. At the core of the system is the RC2014 Backplane, which distributes power and the Z80 bus signals to various custom PCBs and expansion modules. Processing is handled by the Z80 CPU module, which executes instructions and coordinates data flow across the backplane. Visual output is generated by the V9958 graphics chip backed by 192K of dedicated RAM, capable of rendering rich sprites and high-resolution screen modes typical of MSX2 systems. Audio generation is split between the YM2149 sound chip for programmable sound generator effects and the YM2413 OPLL chip for frequency modulation music synthesis. Timekeeping and calendar functions are maintained by the battery-backed RP5C01 Real-Time Clock (RTC) chip. Glue logic is managed by standard logic ICs to handle address decoding, bus arbitration, and chip-select signals across the system. Software-wise, the platform boots using RomWBW HBIOS, allowing the system to interface with standard MSX ROM images and execute MSX-BASIC interpreters, effectively bridging the modular bus design of the RC2014 with the software ecosystem of the MSX standard.
