This is a small PCB for building your own MSX ROM cartridges, perfect for homebrew and small utilities.
- 28-DIP footprint for 64 kB (512 kb) EPROMs, such as 27C512.
- PCB: 65.5mm x 43mm, 30° bevel, immersion gold.
- Cartridge shell: Not included. Designed for Konami-style cartridges.
This circuit is for 64 kB EPROMs, but ROM files smaller than 64kB can be used. If the file
size is 32 kB or smaller, program it starting at EPROM address 4000h.
32 kB (E)EPROMs can also be used, but programming a 32 kB file is not so straightforward, please
check this raphnet.net article
for more information.
Important disclaimer, please read:
You must be able to program and solder your EPROM yourself. We do not provide assistance for this.
If you install a socket, please note that the PCB won't fit in a cartridge shell unless you cut an opening in it.
When using the PCB without a cartridge, make sure to insert the PCB in the correct orientation. Failure to do so may damage the cartridge and/or the computer.
