README.md#reprom64 rom replacement board for the C64
This is a rom adapter board for the C64 which replaces all rom chips with a single 64kb 27C512 Eprom, offering space for four different kernals, four charsets and two basic roms.
It can be assembled for any C64 mainboard as well as for the SX64 CPU board.
Please refer to the project page for detailed documentation.

Questions
How big is the Reprom PCB?
It measures 54.4 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Reprom use?
21 parts, built around the JUMPER3. 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 Reprom KiCad files?
From the hbekel/reprom64 repository on GitHub, at the commit this page was made from: the board is reprom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Reprom design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
