I'm selling this nice MSX2 computer. It is made with a bottom case part, PSU and other hardware from YIS503IIIR, combined with top case part and keyboard from japanese YIS503II : BIOS and subROM was replaced with one from Yamaha YIS604/128 so even if it says YIS503II on the cover you have a real YIS604 inside, with a convenience of using 230V power outage not a 100V. No other modifications, only BIOS change
Price is 225 EUR with shipping to EU included. For other countries i will need to check the shipping prices first. Contact me by mail in my profile
