The Olivetti M20 was a 16-bit computer that was based on the Z-8001 processor, which ran at 4MHz. It came with 128K RAM, which was expandable to 224K. The main console contained the disk drive and the keyboard. A tilt-able VDU screen sat on top of the console, connected by one cable. The M20 came with its own operating system, PCOS (Professional Computer Operating System). The M20 was available with either a single or dual disc drive, as well as a hard disk version. The twin-floppy version was sold for £2,395 plus VAT in the UK.
After a three year development period, the machine was finally released on March 31st 1982, with an expected price range of 3-6000 dollars. Although initially well received, the Z8001 processor and Olivetti's own OS severely hampered the machine.
Olivetti supported the machine with their own software packages such as a word processor by SofSys called Executive Secretary, followed later by another word processor, OliWord, and business software, Olibiz. There was also Microsoft Basic 5.2 with full support for the hardware's features. To alleviate a lack of applications, Olivetti sold a CP/M emulator for US$300.
Around 50,000 computers were sold in the first year.
