I have an MSX2 WavyJ23 Sanyo. Sorry. I am not going to slash, hacked and do surgery to my computer. I only do upgrades by cartridges. That is that. If there is no cartridge upgrade, then so be it.
About a year ago, mr Nishi showed a MSX3 cartridge for existing machines. Haven't heard about it since. It's even unknown if this will be a full MSX3 upgrade or just the IOT part. Maybe we get lucky...
