Notable chips on the board include: Ricoh RP2A03G 8-bit, 1.79 MHz CPU
  • Notable chips on the board include:

  • Ricoh RP2A03G 8-bit, 1.79 MHz CPU

  • Ricoh RP2C02G-0 8-bit, 5.32 MHz PPU

  • Toshiba TC40H368P hex bus buffers

  • Sharp LH5216D-12 static RAM

  • Hitachi HD74LS139P decoder/demultiplexer

  • Fujitsu MB74LS373

  • Unsurprisingly, lead solder abounds on the bottom of the board. RoHS standards weren't established until 20 years after this puppy was made.

主要的芯片如下

日立RP2A03G 8位1.79 MHz CPU

日立 RP2C02G-0 8-bit, 5.32 MHz PPU(图像处理器)

东芝 TC40H368P 六总线缓冲器

夏普LH5216D-12 静态随机存取存储器

日立HD74LS139P 解码器/信号分离器

富士通MB74LS373

毫不意外,主板上有大量的铅焊,毕竟RoHS标准在这个玩意儿诞生20年后才建立的啊
