This is just a simple backup of all the files related to the Centurion that I have stored on my HD. The Wiki itself has far more in-depth information about the Centurion and it's individual cards.
kev-ju/PC-Retro-MTM
Modern KiCad version of the IBM 5150 system board originally created by MTM Scientific, Inc.
332 parts, built around the 74LS384N, 74LS74PC, 74LS00SC and 74LS02PC. 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 ForgottenMachines/Entrex repository on GitHub, at the commit this page was made from: the board is Mystery Test Board/Rollbacks/Rogelio Pineda part 7-AMLDC-2044B.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask ForgottenMachines before reusing the design.
