About the MUTIF09 Single Board Computer
MUTIF09 Single Board Computer is an open source PCB design by ja1umi, published on GitHub under the MIT license. It is a 2-layer board measuring 155 × 114 mm, with 68 components from 41 distinct parts.
Other key parts include the 8MHz, MC6809, MC6850, 1.8432MHz and 8255A. By type, the board carries 22 capacitors, 16 ICs, 16 resistors, 8 connectors, 2 jumpers and 2 diodes.
From the project
Various design materials for building my 8-bit-microprocessor-based single board computer(s)
MUTIF09 (or shortly MUTIF) project is my hobby project for developent of tiny homebrew computers and their add-on/expansion boards (e.g. Arithmetic coprocessor and I/O expansion board) simple enough for building and maintenance, focusing on around 1980s-era microprocessors (e.g. Motorola's MC6809, Harris' HD-6120) just for fun.
Updates are available when they are released.
