CFT MEM Board
About the CFT MEM Board
CFT MEM Board is an open source PCB design by alexiosc, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 233.4 × 280 mm, with 96 components from 9 distinct parts.
Other key parts include the ATF16V8B, 29W040 and AS6C4008-55PCN. By type, the board carries 50 capacitors, 41 ICs, 4 connectors and 1 jumper.
It belongs with the usb & debug tools designs in this gallery.
From the project
The CFT homebrew minicomputer
The CFT is a home-designed, home-built mini-computer made from scratch.
I've designed and built the instruction set, data path, processor, computer, software stack, cross-assembler, emulator, software toolchain and even some of the tools needed to do all this. You can call this a ‘fantasy mini’.
This project has been going since approximately 2001, in my Copious Free Time.
