Από τις μεγαλύτερες κοτσάνες που διάβασα εδώ μέσα : "Ο spectrum δεν είχε επεκτασιμότητα"
Έλεος, μάλλον δεν έχεις επαφή με το φαινόμενο spectrum Mr Sh(p)ock
Several peripherals for the Spectrum were marketed by Sinclair: the ZX Printer was already on the market,[20] as the ZX Spectrum expansion bus was backwards-compatible with that of the ZX81.
The ZX Interface 1 add-on module included 8 kB of ROM, an RS-232 serial port, a proprietary LAN interface (called ZX Net), and an interface for the connection of up to eight ZX Microdrives — somewhat unreliable but speedy tape-loop cartridge storage devices released in July 1983.[21][22] These were later used in a revised version on the Sinclair QL, whose storage format was electrically compatible but logically incompatible with the Spectrum's. Sinclair also released the ZX Interface 2 which added two joystick ports and a ROM cartridge port.[23]
There were also a plethora of third-party hardware addons. The better known of these included the Kempston joystick interface, the Morex Peripherals Centronics/RS-232 interface, the Currah Microspeech unit (speech synthesis),[24] Videoface Digitiser, RAM pack, and Cheetah Marketing SpecDrum (Drum machine), and the Multiface (snapshot and disassembly tool), from Romantic Robot.
There were numerous disk drive interfaces, including the Abbeydale Designers/Watford Electronics SPDOS, Abbeydale Designers/Kempston KDOS and Opus Discovery. The SPDOS and KDOS interfaces were the first to come bundled with Office productivity software (Tasword Word Processor, Masterfile database and OmniCalc spreadsheet). This bundle, together with OCP's Stock Control, Finance and Payroll systems, introduced many small businesses to a streamlined, computerised operation. The most popular floppy disk systems (except in East Europe) were the DISCiPLE and +D systems released by Miles Gordon Technology in 1987 and 1988 respectively. Both systems had the ability to store memory images onto disk snapshots could later be used to restore the Spectrum to its exact previous state. They were also both compatible with the Microdrive command syntax, which made porting existing software much simpler.
During the mid-1980s, the company Micronet800 launched a service allowing users to connect their ZX Spectrums to a network known as Micronet hosted by Prestel. This service had some similarities to the Internet, but was proprietary and fee-based.
