Beta Disk Interface
Beta Disk Interface is a disk interface for ZX Spectrum computers. It was developed by Technology Research Ltd. (United Kingdom), in 1984 and released in 1985 with price £109.25 (or £249.75 with one disk drive). Beta 128 Disk Interface is a 1987 version supporting ZX Spectrum 128 machines (difference is in access points addresses). Beta disk interfaces were distributed with TR-DOS operating system in ROM, also attributed to Technology Research Ltd. Latest firmware version is 5.03 (1986). The interface was based on the WD1793 chip. The interface handles single and double sided, 40 and 80 track double density floppy disks, up to 4 drives. Clones This interface was popular for its simplicity, and the Beta 128 Disk Interface was cloned all around the USSR. The first known USSR clones were ones produced by НПВО "Вариант" (''NPVO "Variant"'', Leningrad) in 1989. Beta 128 schematics are included in various Russian ZX Spectrum clones. Some variants of schematics support onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CP/M
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/ 85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. The combination of CP/M and S-100 bus computers became an early standard in the microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to install an application on a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their crea ...

IS-DOS
iS-DOS is a disk operating system (DOS) for Soviet/Russian ZX Spectrum clones. iS-DOS was developed in 1990 or 1991, by Iskra Soft, in Leningrad, Soviet Union, now Saint Petersburg, Russia. It handles floppy disks (double sided, double density), hard disk drives, and CD-ROMs. Maximum iS-DOS disk partitioning size on a hard disk is 16 MiB. Unlike TR-DOS, iS-DOS is resident in random-access memory (RAM), and thus reduces the amount of memory available for user programs. Versions ''iS-DOS Chic'' is a version developed for the Nemo KAY. It provides more memory for user programs. ''TASiS'', based on iS-DOS Chic, is a modern version developed by NedoPC for the ATM Turbo 2+ in 2006, supports the enhanced text mode and larger memory of that model. Distributors * Slot Ltd. (Moscow) distributed iS-DOS in Moscow and regions in 1990s, and issued paper books. * Nemo (Saint Petersburg) distributed iS-DOS in ex-USSR until 2004, and issued ''Open Letters'' electronic press. * iS-DOS ...

Beta Disk 128C (electronics)
Beta (, ; uppercase , lowercase , or cursive ; grc, βῆτα, bē̂ta or ell, βήτα, víta) is the second letter of the Greek alphabet. In the system of Greek numerals, it has a value of 2. In Modern Greek, it represents the voiced labiodental fricative while in borrowed words is instead commonly transcribed as μπ. Letters that arose from beta include the Roman letter and the Cyrillic letters and . Name Like the names of most other Greek letters, the name of beta was adopted from the acrophonic name of the corresponding letter in Phoenician, which was the common Semitic word ''*bait'' ('house'). In Greek, the name was ''bêta'', pronounced in Ancient Greek. It is spelled βήτα in modern monotonic orthography and pronounced . History The letter beta was derived from the Phoenician letter beth .

ZX Spectrum
The ZX Spectrum () is an 8-bit computing, 8-bit home computer that was developed by Sinclair Research. It was released in the United Kingdom on 23 April 1982, and became Britain's best-selling microcomputer. Referred to during development as the ''ZX81 Colour'' and ''ZX82'', it was launched as the ''ZX Spectrum'' to highlight the machine's colour display, which differed from the black and white display of its predecessor, the ZX81. The Spectrum was released as six different models, ranging from the entry level with 16 Kilobyte, KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and built in floppy disk drive in 1987; altogether they sold over 5 million units worldwide (not counting List of ZX Spectrum clones, unofficial clones). The Spectrum was among the first home computers in the United Kingdom aimed at a mainstream audience, and it thus had similar significance to the Commodore 64 in the US and the Thomson MO5 in France.
