Olivetti typewriters
Olivetti is an Italian manufacturer of computers, tablets, smartphones, printers, calculators, and fax machines.
It is characterized by the various colors available: in addition to the classic black, it was also available in red, gray, brown and light blue.
This machine was first published as M80, featuring a keyboard with round keys that had a thin metal outline to the circunference, appealing notoriously to many older models, like the M40.
The Lexikon 80 had a few changes in contrast to its previous version M80; it had keys fully made out of plastic, it was slightly bigger in size, it startedmost featuring decimal tabulators, and it had a wide variety of dismountable carriages.
The Olivetti Lettera 22 [oliˈvetti ˈlɛttera ˌventiˈduːe] is a portable mechanical typewriter designed by Marcello Nizzoli in 1949 or, according to the company's current owner Telecom Italia, 1950.
The typebars strike a red/black inked ribbon, which is positioned between the typebar and the paper by a lever whenever a key is pressed; a small switch located near the upper right side of the keyboard can be used to control the strike position of the ribbon, in order to print with black, red, or no ink (for mimeograph stencils).
The Lettera 32 that he purchased in 1963 was auctioned at Christie's on December 4, 2009, to an unidentified American collector for $254,500, more than 10 times its high estimate of $20,000.
[11] Francis Ford Coppola used an Olivetti Lettera 32 to write the screenplay for the 1972 motion picture The Godfather, which he also directed.
The Olivetti Lettera 35 is a portable mechanical typewriter created in 1972 by Mario Bellini and released to the public in 1974.
Two mechanical sensors located near each spool move when the ribbon stretches (this indicates that it is finishing) and reverse its winding direction.
Despite being an expensive, functionally limited and somewhat technically mediocre product which failed to find success in the marketplace, the Valentine ultimately became a celebrated icon — largely on account of its expressive design and practicality.
The Editor 5 from 1969 was the top model of that series, with proportional spacing and the ability to support justified text borders.
In 1972 the electromechanical typeball machines of the Lexicon 90 to 94C series were introduced, as competitors to the IBM Selectric typewriters, the top model 94c supported proportional spacing and justified text borders like the Editor 5, as well as lift-off correction.
The typewriter was controlled by the computer by additional electromechanical components at the keyboard levers at the bottom of the machine.
The degrees to rotate the typeball was depending on this coding, using levers with moving turnpoint when pressing a key.
This was the top model of the series providing proportional spacing and block aligned text similar to the Editor 5.
Portable compact electrical typeball machine, successor of Lettera 36, implementing the IBM selectric 'golfball' mechanism, after its patent ended.
Later the ET series typewriters without (or with) LCD and different levels of text editing capabilities were popular in offices.
The 5,25 inch single sided boot diskette starts directly in the MWP called wordprocessing software.
A rare version is the diskless ETV 300 which used to have the operating system and MWP in a ROM and storing the documents in battery buffered SRAM.
The base configuration is diskless, storing all saved documents in battery buffered 32 kB RAM.
This configuration can be enhanced by adding one 360 kB single sided 3.5 inch floppy drive supporting the same disk and document format as ETV 350.
SWP supports to include tables which also could be used to print simple line based graphics in a document.
Computer and printer are integrated in one box, like on ETV 240/250 the monitor can be installed on an arm and the keyboard is similar to IBM's XT layout.
Optionally, there was an external 360 kB 5.25 inch floppy drive called DU 260 to support diskettes of ETV 300 for document import.
With its thermo transfer print head, based on IBM's quietwriter patents combined with the printer chassis of ET 116 the ETV 210s was announced as the future of the typewriter.
The PC style external keyboard is quite special as it contains 80x5 characters alphanumeric LC display to write the documents.
[26] The machine is a fully integrated, NEC V40-based PC, with the electronics to control the printer on one small footprint mainboard.
As mass storage there could be one 720 kB MS-DOS compatible floppy drive, or two of them, or one of them plus 20 MB XTA interface based harddisk.
This is same like ETV 2900, the only difference is modified BIOS to prevent user to boot from standard MS-DOS diskettes.
