Yamaha MSX mini cartrige PCB and connector for CX5M CX7M YIS-503 YIS-604 ROM DIY

Description

Cartridge PCB for Yamaha CX5M CX7M CX5MII CX7MII and compatible MSX computers with a 30-pin front mini cartridge slot (not the large MSX top slot)
This listing includes  PCB + 30-pin angle connector. If you just need the board, look for my other listing.
The board has the same form factor as Yamaha's YRM-502 cartridge. It will accept 27C128-27C512 EPROMS and solder jumpers allow flexible configuration (multiple images in one ROM, etc.)
You can use the board to make your own cartridges for your Yamaha MSX music computer, including
