Register+TristateBuffer
About the Register+TristateBuffer PCB
Register+TristateBuffer is an open source PCB design by SABRINIAC, published on GitHub. It is a 2-layer board measuring 89.3 × 99.9 mm, with 203 components from 4 distinct parts.
By type, the board carries 134 resistors, 67 transistors and 2 connectors.
From the project
It is for my '60s inspired computer im making base don the Intel 8080. At the time of writing this I have RAM + it's clock done and the ALU Modules done. After I get the registers + buffers I'll only have to make a motherboard and an opcode decoder/microcode.

The SABRINIAC is my '60s inspired, transistor based,, Intel 8008 Architecture computer. Every part of it from the instruction decoder to the alu will be built using purely transistors.
