New board

A project log for Lion FPGA CPU/Computer

A 16-bit (and a 32bit) FPGA CPU I call Lion CPU and a computer, the Lion computer. Everything built from scratch.

I made a new base board for Lion32, a 4-layer one. In this board there is a ground layer and I mixed the sound channels, noise and digital sample output to a stereo sound output. It also features a 1MByte static RAM and a second serial port.

 I ordered the pcb from PCBWay as I have done so far for all my projects and I am very pleased with their service and the quality of the results.   

This is a project I enjoy to keep returning to between my other projects mostly for retro computers.

I received and tested the board, everything fine,  1MB ram available now and the system is more "quiet".
