A 6507-based single-board computer with 128 bytes RAM, 7KiB ROM, I/O, graphics and sound. As an added challenge, it was built with the requirement to not contain any IC larger than DIP-28.
Hardware contains the KiCad project files for the SBC itself, as well as the adapter board for the supported SPI peripherals.
Programs are programs written to test various features of the SBC.
Verilog contains a basic Verilog implementation of the 6507, and the pixel LCD peripheral. Used during software development when ROM swapping became too tedious. Doesn’t implement undocumented instructions or decimal mode.
