This is proof of concept microcomputer. A boilerplate of future "Multiputer".
As this is experiment, we will test following hardware and/or software and/or technology.
- Serial communication build on 16C550 or similar.
- Connect RAM and EEROM in the simplest possible way.
- Test the tools (assembler, linker) and create basic firmware.
- Create of bus of some sort for interconnection a bunch of microcomputer.
The five basic breadboard were assembled together. On the left one you can see voltage regulator build on chip 7805. On the right you can see the main microprocessor 6809 with crystal. Currently the crystal is 3.57 MHz because 8MHz crystal was not found.
