Sanyo Wavy 23 – MSX 2

The Sanyo Wavy 23 was the first MSX I got for my collection. It is completelly functional and in awesome cosmetic condition with basically no signs of aging. I also got the box and manual, which do show some wear and tear but are still in pretty good condition:

Internally, this machine is a pretty standard MSX 2 computer for 1985: 64Kb of RAM, 2 cartridge slots, RGB / Composite and RF video output and the usual MSX-Basic in ROM. What is really cool about it is the case design. It has this weird angular shape, with some extra area over the right side, both on top over the slots and at the bottom under the arrows (maybe to serve as a wrist support?).

As you can see the model I have is the dark gray case with light gray keys. There was also a blue model (see pictures at which apparently had the exact same specs.

Overall this is a solid MSX 2 that has some additional collector value due to its unusual design.
