The Olivetti M-10 is basically the same computer as the Tandy 100 or the NEC PC-8201. All these machines were in fact conceived by Kyocera Corporation (Japan). Thus they all have very similar characteristics. Olivetti is well known for computers with special design, and the M-10 is not an exception. Compared to the Tandy 100 or NEC PC-8201, the M-10 is quite beautiful. The main physical difference is the LCD screen which can be tilted for user's comfort.
