openPCIE

by chili-chips-ba

Peripheral Component Interconnect (PCI) has taken the Express lane long ago, moving to xGbps SerDes. Now for the first time in opensource on the Host side too. Our project roots for the Root Port in 4 ways: |1|openRTL |2|openBFM with unique SIM setup, way faster than vendor's |3|openSW stack |4|one-of-a-kind open backplane.

C64 Lumafix

by tebl

An easier to solder version of the Lumafix board, components spaced out a bit more to make things easier on the beginner (mostly meaning me). Can also be used to bypass noisy signals on motherboard, wireing directly to modulator replacement.
