Sanyo Wavy 35 – MSX 2+

The Wavy 35 is the “poor cousin” of all MSX 2+. It is the only model that doesn’t have a disk drive and one of two (the other being the Panasonic FS-A1FX) without MSX-Music. However, that is not a reason to ignore this machine. It is actually a pretty difficult machine to find (especially in good state) and since most issues with old MSX computers are related to disk drives, this machine is usually a lot easier to maintain than the others. Furthermore, the Sanyo models (Wavy 35, 70FD and 70FD2) have one of the best keyboards available amongst all MSX 2+ machines.

I got my computer directly from Japan and it is in pretty good shape. One challenge with these machines is the way their cases were painted. It is a very sensitive finishing that comes off pretty easily. You got to be very careful when using any sort of cleaning product, including alcohol which is usually safe.
