      **The electronic part of the M-10 was made in Japan by Kyocera Cie.**

      **(1)** System init button (Reset).\
      **(2)** Four 1.5v battery cells provide 20 hours of work in running mode, or 80 hours in sleep mode.\
      **(3)** Serial RS-232 connector.\
      **(4)** Parallel Centronics printer connector. As it is not a standard connector, a special Olivetti cable is needed.\
      **(5)** Cassette recorder DIN connector with remote control. Data transfer speed is of 1500 baud (about 190 char./second).\
      **(6)** Bar code reader connector.\
      **(7)** A 8 Kb. RAM expansion chip can be plugged to each of these three sockets. Originaly, a 8Kb. RAM chip is already mounted on the left one. Thus, a maximum of 32 Kb RAM can be installed.\
      **(8)** This socket can receive an additional 32 Kb ROM chip. The original 32 Kb ROM holds the built-in software and the Microsoft Basic interpreter.\
      **(9)** 80C85 low power CMOS 8 bits microprocessor, running at 2,457 Mhz.\
      **(10)** External power supply unit connector.

      Like Philips which sold in Europe a part of its products under Radiola or Schneider brands name, or even Sharp which sold its pocket computers under Tandy's name with minor design changes; these three computers (<$475$>Olivetti M10, <$334$>NEC 8201, <$233$>Tandy Model 100) are, in fact the same model, manufactured by Kyocera.

      If the hardware part is basically the same, external design is slightly different. Olivetti offered a tilting display and Nec added arrow keys. The main purpose of this partnership was to reduce research & development and manufacturing costs. The same model, designed and manufactured by a single company could have been 25% more expensive.

      Ack! Sorry, I just realized that you posted that offer in 2007. I guess I''m a little late there.

      You were also offering an M15, not an M10. I blame the months of April.

      If anyone does have an m10 they want to part with, catchingtech@gmail.com .

      I own an Olivetti M15 laptop, A dual 720kByte floppy based PC. This is possibly the best laptop from the 80's in my opinion!

      If anyone wants it, its free to a good home, you just need to pay the postage. email me for more details.\

The Olivetti M-10 is basically the same computer as the [Tandy 100](/museum/tandy-radio-shack-trs-80-model-100-102/) or the [NEC PC-8201](/museum/nec-pc-8201a/). 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.

Just like its brothers, the M-10 was used a lot by reporters all around the world. This success was mainly due to its excellent keyboard and large battery autonomy.

The M-10 a some built-in software :\
\- An Extended Microsoft Basic\
\- A wordprocessor\
\- A small spreadsheet (adress files)\
\- An Agenda\
\- And a communication program.

The M10 had 4 standard RAM/ROM sockets, whereas all other Kyocera machines had specific RAM or ROM sockets.

The french model doesn't seem to have the modem built-in as it is the case for the "normal" M-10. This is maybe because any Modem sold in France had to be "agreed" by the French Post Office (!), which was a difficult task...
