A (Sept.) 1985 Yamaha MSX presented with a mouse – a rare conjunction mayhaps. Giving me Amiga tank mouse vibes. The Amiga 1000 came out in July, and originally with only 256KB RAM iirc. Its sound and graphical chipset was more impressive than MSX2 I'd say.
Looks like around 200K¥ for the bundle below. Hard to guess what that is in modern money since something happened to the yen in 1985 (the Plaza Accord).
@androidarts he also did many designs for the Turn-A Gundam anime!
