DOS Palmtop: Mitsuba Palmtop Details and specs

Mitsuba Palmtop

About this machine:

One of the few American TidalWave clones. There is not really much info about Mitsuba left since the name is kind of generic and some Japanese companies are called Mitsuba as of today, but if you dig long enough then you eventually find the truth. In a 1987 ad in PC Magazine their catchphrase was "Mitsuba - a name to remember". Well didn't work i guess... Besides the name Mitsuba was not a Japanese company, it was a company in California. They appeared somewhere in the mid 1980s under various names like "Mitsuba Semiconductors", "Mitsuba Corp" and so on, always based in San Dimas in California. At some point they also had offices in New Jersey and Texas, so they were a rather small player, but not a "garage company" like ProLinear or so. As it seems they never really manufactured anything, they just sold imported hardware that they branded. In the late 1980s they had quite affordable complete PC sets in their portfolio and i believe they were halfway successful with what they did. But the Tidalwave curse hit them as well. If you read most of my articles here you already know that ironically most companies that sold TidalWave palmtops went bankrupt later on and Mitsuba is no exception here. The Mitsuba Palmtop was pretty much their last sign of life, they disappeared somwhere in the early to mid 1990. Like most TidalWave clones the branding is rather cheap - they printed "Mitsuba" under the display and that's it. English OS and appz, American keyboard.

One of the rarest TidalWave clones. Hey at least it's an American version. Otherwise pretty much like all other TidalWave clones.
