jblang/805118051 board for RC2014
8051 is an open-source printed circuit board by jblang, from the jblang/8051 repository on GitHub. It is a 2-layer board of 99.1 × 49.9 mm with 15 parts on 50 nets, routed with 437 tracks and 9 vias.
It is built around the DS80C320-ENL+, 74LS373SC and 74LS04PC. Its parts include 6 capacitors, 4 ICs, 3 connectors and 1 crystal.
This is a board design for an 8051 (specifically, for the Maxim DS80C320). I had the board manufactured but initial bringup was not successful, and I have not had time to debug it. I am posting on GitHub as a backup in case I ever get back to it, or in case anyone else wants to take it further.

It measures 99.1 × 49.9 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the DS80C320-ENL+, 74LS373SC and 74LS04PC. 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.
From the jblang/8051 repository on GitHub, at the commit this page was made from: the board is 8051.kicad_pcb and its schematic 8051.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask jblang before reusing the design.
