Description
**This is a hobby project and comes with no official support. The PCB schematic and board design files are offered 'as is' with no claims made about their fitness for any specific purpose.** The Multicomper motherboard is a simple platform for creating a 'Multicomp' computer based on the design work of Grant Searle - which can be found here: http://searle.x10host.com/Multicomp/index.html ![zpmcomper0.png](//image.easyeda.com/pullimage/yIkZWmozmg3xdngaaOGMANjx4p0h6Dd0zO7sujjT.png) The Multicomper holds all the components and connectors needed to create a Multicomp-based designs (Z80, 6809, 6502 etc.). The main part needed is a low-cost Cyclone II development board from your favourite auction site or other supplier - search for *EP2C5T144C8N mini board*, but do **read the notes on the Github page below BEFORE ordering**. The Multicomper has the following additional features: - A prototyping area. - All spare FPGA pins are broken out to headers do you can use them for your own purposes. - A ‘key’ (reset) button in parallel with the one on the FPGA board. - An optional regulated 5V power circuit in case you need it. - A micro-SD card slot. - Two serial port headers (NB: 3.3V logic like all the I/O). - VGA and PS/2 keyboard port. - Composite video header. - Second SPI port with separate CS header pin (link it to the FPGA pin of your choice). **FOR MORE DETAILS AND IMPORTANT CONSTRUCTION NOTES, SEE: https://github.com/linker3000/Multicomper**
