Technical specifications

The Olivetti M15 portable Personal Computer is the answer to your computing problems even when you are out of the office.
* A truly portable PC both in weight and size
* Professional performance O A complete standard configuration
* Dual compatibility (3.5" and 5.25" floppy disks)
* Dual power supply (from mains or rechargeable batteries)
* Ergonomic design.
Although small in size, the M15 is a true professional Personal Computer,
Thanks to the new advanced technology - Surface Mounted Device - it has been possible to design a portable, compact Personal Computer that still has the performance of a desk-top PC.
Since either 3.5" or 5.25" floppy disks can be used, total compatibility with industry standards is guaranteed, thus enabling you to interchange jobs on the M15 with any other industry standard PC. The M15's central processing unit is the CMOS Intel 80088 and the operating system is MS-DOS 3.2 - the most recent MS-DOS release which, as well as allowing simultaneous management of two different format drives, capitalizes fully on the M15's potential.
In other words, with the' dual compatibility feature, the M15 can exploit the dual software library (3.5" and 5.25") developed for the MS-DOS standard. You can continue to run alt the programs you use in your office on this portable PC, which has 512 K memory as standard.
The M15 offers you a detachable, professional keyboard with 78 keys, 10 function keys and an integrated numeric pad, and is available in different national layouts.
The antiglare, tiltable display is the largest LCD used in Personal Computers and features a standard 25 line x 80 character format.
Graphic resolution is 640x200 pixels. Since different "shades of grey" can be displayed, software compatibility is guaranteed.
Inside the M15 there are two disk drives for 720 K 3.5" minifloppy disks.
Externally the M15 can be connected to a 5.25" floppy disk drive, thus enabling data and programs also to be transferred to systems with different disk formats. The dual power supply - mains or batteries - increases the portability of the M15. In fact, the rechargeable batteries ensure total independence for 6 hours. Recharging, via the external power supply unit connected to the mains, can be carried out with the system either on or off.
Connection to any type of printer or peripheral unit, the interfaces supplied as standard is ensured by the interfaces supplied as standard in the basic configuration: RS 232 C and CCITT V24 serial interface for asynchronous communication and Centronics parallel for printers.
From the ergonomic point of view, every effort has been made to ensure that you can work in comfort wherever you are.
