About the Micro 8088 PCB

Micro 8088 is an open source PIC PCB design by skiselev, published on GitHub under the GPL-3.0 license. It is a board measuring 152.4 × 101.6 mm, with 71 components from 44 distinct parts.

Its main chip is the PIC12F629, from the PIC family. Other key parts include the 8088, 8087, FE2010A, SST39SF010A and AS6C4008. By type, the board carries 23 capacitors, 16 ICs, 8 resistors, 4 jumpers, 3 connectors and 3 switches.

From the project

Micro 8088 - IBM XT Compatible Processor Board based on Faraday FE2010 chipset

Please refer to Building Instructions page for detailed instructions.

Please refer to Faraday FE2010A documentation and Faraday FE2010 datasheet for detailed information about Faraday FE2010/FE2010A chipsets.

Note: CPU clock frequency switching (turbo mode) is only implemented in Faraday FE2010A chipset (not in FE2010).

Note: To enable internal speaker connect a jumper across pins 1-2

Micro 8088: common questions

What microcontroller does the Micro 8088 use?

The Micro 8088 is built around the PIC12F629, from the PIC family.

How big is the Micro 8088 PCB?

The Micro 8088 measures 152.4 × 101.6 mm and is 1.6002 mm thick.

How many components are on the Micro 8088?

71 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Micro 8088 design files?

From the skiselev/micro_8088 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Micro 8088 design in my own project?

Yes, under the terms of its GPL-3.0 license, which skiselev chose for the repository.

Can I test firmware for the Micro 8088 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
