Overview
Cococpld is an open-source printed circuit board by mattstock, from the mattstock/cococpld repository on GitHub. It is a 2-layer board of 83.3 × 98.3 mm with 60 parts on 134 nets, routed with 3 tracks and 0 vias.
It is built around the R1LP0108ESF-5SI#S1 and TLV1117-33DCY. Its parts include 15 capacitors, 15 connectors, 13 diodes, 6 ICs and 5 resistors. It belongs with the interfaces and adapters boards and the AVR (ATmega, ATtiny) and FPGA and CPLD boards of this library.
Main components
2README
README.mdcococpld
A complete bus interface design and floppy drive emulator for the Tandy Color Computer using Arduino/AVR!
This is a combined open source/open hardware project to design a development board for a variety of 8- and 16-bit computers, starting with the Tandy/TRS-80 Color Computer.
Videos of how these components work together are available at https://www.youtube.com/user/Greyhound716.
Directories:
firmware2 - AVR gcc project for the firmware to act as FDC and ROM programmer. fpga - Altera Quartus project to implement the control logic for the board. kicad - Kicad project including the schematics and board layout. cpld - Some legacy stuff, for some earlier attempts to build the logic using small CPLDs.

Questions
How big is the Cococpld PCB?
It measures 83.3 × 98.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cococpld use?
60 parts, built around the R1LP0108ESF-5SI#S1 and TLV1117-33DCY. 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 Cococpld KiCad files?
From the mattstock/cococpld repository on GitHub, at the commit this page was made from: the board is kicad/cococpld.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cococpld design in my own project?
Its repository states no licence, so its author keeps all rights: ask mattstock before reusing the design.
