README
README.mdModular 8-bit Computer
This is the repository for an 8-bit computer system that is built using cards with a standardized interface.
- CPU card
- Protoboard card
- This card contains an onboard clock generator, address and data registers/buffers, and a protoboard area for testing designs.
- Bus interface modeling
Here's an example of a card:
Current Bus Specification
// The main bus wires (32+8=40 wires total)
// On the bus connector, all buses have LSBs closer to the power pins and MSBs farther away
wire VCC_5V;
wire GND;
wire clk; // generated by motherboard clock generator
wire rst_n; // probably a button on the motherboard
wire VCC_3V3;
wire we_n; // active LOW
wire oe_n; // active LOW
wire int_n; // pulled up by motherboard; driven down by any peripheral (could be used for interrupts)
wire [7:0] data;
wire [15:0] addr; // 64k address space is suppored by default. More address bits may be added later
wire [7:0] aux_bus;Parts

Questions
How big is the ISABLE LIGHTER PCB?
It measures 31.6 × 31.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ISABLE LIGHTER use?
22 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ISABLE LIGHTER KiCad files?
From the ethanjamesauto/modular_8bit_computer repository on GitHub, at the commit this page was made from: the board is ISABLE LIGHTER/ISABLE LIGHTER.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ISABLE LIGHTER design in my own project?
Its repository states no licence, so its author keeps all rights: ask ethanjamesauto before reusing the design.
