Micro 8088 is an easy to build IBM PC/XT compatible processor board. It is based on Faraday FE2010/FE2010A or Proton PT8010AF chipset, that implements most of IBM PC/XT LSIs (Intel 8xxx ICs) and glue logic. Micro 8088 uses SRAM ICs to implement the system RAM, and a Flash ROM IC to store the BIOS, further reducing the number of components, and simplifying the build process.

Specifications

Processor: Intel 8088 or compatible, NEC V20

• Supports IBM PC/XT standard 4.77 MHz CPU frequency and, when using FE2010A chipset, 7.16 MHz and 9.54 MHz CPU frequencies
