List of ZX Spectrum clones

The following is a list of clones of Sinclair Research's ZX Spectrum home computer. This list includes both official clones (from Timex Corporation) and many unofficial clones, most of which are coming from Eastern Bloc countries. But does not include computers that need an additional hardware or software add-ons to run the ZX Spectrum.

OfficialEdit

 
The Timex Sinclair 2068

The only official clones of the Spectrum were made by Timex. There were three models developed, only two of which were released:

Timex Sinclair 2068Edit

A significantly more sophisticated machine than the original Spectrum. The most significant changes were the addition of a cartridge port, an AY-3-8912 sound chip and an improved ULA giving access to better graphics modes. The TS2068 was marketed in the United States, while very similar machines were marketed in Portugal and Poland as the Timex Computer 2068 (TC2068) and Unipolbrit Komputer 2086 (UK2086) respectively. A small amount of TC2068 were also sold in Poland.

Timex Computer 2048Edit

A machine similar to the Spectrum 48K, but with the improved ULA from the TC2068 allowing access to the improved graphics modes. Marketed only in Portugal and Poland.

Timex Sinclair 2048Edit

A never released variant of the TS2068 with 16 KB of RAM.

Inves Spectrum +Edit

 
Inves Spectrum +

A clone of the ZX Spectrum+ developed by Investrónica in Spain in 1986, based on the work developed by Investrónica for the ZX Spectrum 128. Released just after Amstrad bought Sinclair Research Ltd, looked much like a normal 48+, but all the inner parts were redesigned. As the ROM was also modified, it has compatibility problems with some games (Bombjack, Commando, Top Gun, etc.).[1] On the rear there was a Kempston joystick connector.

Due to the fact that Invéstronica was the distributor of Sinclair's products in Spain, and because Amstrad already had its own exclusive distributor in Spain (Indescomp, later bought by Amstrad itself), in 1987 Amstrad sued Investrónica to stop the sale of the computer.[2] The court agreed with Amstrad, but the decision was not issued until 1991, when the computer was discontinued as the 8-bit computer market in Spain was dead in favor of 16-bit computers.

Decibells dB Spectrum+Edit

 
Decibells dB Spectrum+

An official clone of the ZX Spectrum+ for the Indian market.

UnofficialEdit

CzechoslovakEdit

Bobo64Edit

An advanced Czech computer compatible with the ZX Spectrum, developed by Václav Daněček in 1986-1987. It has many enhancements, incl. 256*256 graphics with attributes per 8*1 pixels and 512*256 graphics. Unlike other Czecho-slovak home-made ZX Spectrum clones, the Bobo64 gained some popularity and was made by dozens of enthusiasts.[citation needed]

Didaktik GamaEdit

The Didaktik was a series of home computers produced in Skalica, former Czechoslovakia, now Slovakia. The first model compatible with the ZX Spectrum was the Didaktik Gama, based on the U880 or Zilog Z80 processors and the original ULA chip. It was produced in three variants of years 1987, 1988 and 1989. The Gama has a built-in 8255 chip (used for the Kempston joystick and also as a printer port) and 80KB RAM, adding an alternative memory bank from the address 32768 to 65535.

Didaktik MEdit

The Gama was followed by a cheaper Didaktik M (first variant released at 1990, second variant released at 1991). The model M had a modernized case, Sinclair and Kempston Joystick ports and a keyboard with cursors and reset key (but in a less quality design than the Gama). Its screen aspect ratio and display timing is different from the original ZX Spectrum because the M uses different ULA chip, compatible with the Russian clone Baltik. Last model was Didaktik Kompakt (1991) which integrated all previous M hardware with a 3,5 floppy disk and the soundchip AY-3–8912.

Didaktik 192KEdit

Unlike previous versions, this was an amateur project, partly combining hardware of the Didaktik Gama and the ZX Spectrum 128K.

KrišpínEdit

A Czechoslovakian clone of ZX Spectrum, developed by František Kubiš at 1984, student of EF SVŠT (Electrotechnical Faculty of Slovak Technical University) Bratislava. ULA designed from discrete 74xx ICs, screen part or RAM was synchronized perfectly, without CPU blocking.[citation needed]

MistrumEdit

A Czech clone of the 48K ZX Spectrum. The ROM include also chars with Czech diacritic marks. An article on how to build a Mistrum was published in the Czechoslovak amateur radio magazine Amatérské Radio nr 1/89. This magazine article has been translated into the English language: (archived) or via ftp. As the Mistrum was an amateur hardware design they may look very different as each builder made his own case and keyboard.

NucleonEdit

A clone of the Pentagon 512K, made by CSS.

Sparrow 48KEdit

The first clone of the ZX Spectrum, which was designed to replace original motherboards in standard and Spectrum+ cases. The author is Jiiira. Developments were completed and production began in 2013. In addition to the use of the original ULA chip, this clone was heavily modernized, replacing part of the larger glue logic with one CPLD chip, a whole main memory with one SRAM chip and all 8 video memory chips with a second SRAM. A TV modulator has been dropped and replaced by a video signal. Also a power supply part was completely changed and improved. The Sparrow offers a bigger ROM (switchable per 16 KB, by a switch or a jumper).

RomanianEdit

CobraEdit

A ZX Spectrum clone built in Braşov, Romania.HCM: East-European Home-Computer ...[1][3]

CIP-03Edit

A Romanian ZX Spectrum clone made by Intreprinderea Electronica. It is called 'Calculator pentru Instruire Personală' which means 'computer for personal teaching'. The keyboard looks nice, but the key switches are very simple and therefore so is the 'feeling'. A nicely built PCB with 45 chips (most 74-family) inside. The ROM is original Sinclair, although instead of the Sinclair copyright message, it states 'BASIC S'. Only one set of 8× 1-bit 64 KB RAMs present. The power supply is the size and weight of a couple of bricks including a huge transformer unlike the now-standard switching power supply.

Felix HC seriesEdit

A series of ZX Spectrum clones was manufactured in Romania from 1985 to 1994, by ICE Felix. The designation HC means Home Computer, and for the first three models in the series, the number is the year of first manufacture. Models in the series were: HC 85, HC 88, HC 90, HC 91, HC91+ (HC128), HC 2000, HC386.

The earliest version, HC 85, closely resembled the Spectrum, with a built-in BASIC interpreter, Z80A processor, 48 KB RAM, tape, and TV interfaces.[4] It was used in schools/universities and as a personal computer.

An optional Interface 1 extension was available for the HC 85, HC 90, and HC 91. It was functionally similar to the ZX Interface 1, but instead of Microdrives it supported single-density or double-density floppy disks.

The HC 90 had a redesigned circuit board supporting fewer, larger memory chips; it was functionally equivalent with the HC 85.

The HC 91 had a modified keyboard with 50 keys instead of 40. It had 64 KB RAM and extra circuitry which provided CP/M support, if the Interface 1 extension was also present.

The HC 2000 (manufactured from 1992–94) had a built-in 3.5-inch 720 KB disk, and 64 KB RAM, it could be used both as a Spectrum clone with added disk functionality (only 48 KB RAM available) or in CP/M mode, giving access to the full 64 KB memory. Essentially, it brought the HC 91, Interface 1, and floppy disk in a single case.

The last model to be made in the Z80 line was the HC91+. It was a ZX Spectrum 128K clone in a HC91 case and keyboard and had some compatibility problems. For the first time, the AY-8910 sound chip was offered as an add-on service and was soldered on the board by factory technicians. Demoscene demos had problems running multi-colour effects and displaying sound VU-meter like effects lacking some data from the AY chip probably.

JETEdit

A Romanian clone. Developed by the Romanian TV factory.

TimSEdit

TimS was developed around the university of Timișoara in Romania and the name TimS comes from TIMişoara and Spectrum. The models were extended in various ways and production continued into the early 1990s. The computer is fully compatible with ZX Spectrum, but comes with 64 KB RAM. At the back it has Source (ALIM), parallel and serial connectors, cassette player, monitor and TV connector, reset button. Later models have a joystick connection, 192 KB RAM and AY-3-8912 sound chip.

South AmericanEdit

Czerweny CZEdit

The Czerweny CZ 2000, Czerweny CZ Spectrum and Czerweny CZ Spectrum Plus were Argentinian produced clones from 1982 (after the Falklands war) until an electric fire destroyed the factory in Paraná city in June 1986. [5]

Microdigital TK90XEdit

The TK90X was the first Brazilian ZX Spectrum clone made in 1985, by Microdigital Eletronica, a company located at São Paulo, Brazil, that manufactured some ZX81 clones before (TK82, TK82C, TK83 and TK85) and a ZX80 clone (TK80). The ROM were hacked to allow an UDG editor and accented characters (incompatibility issues are very rare or none). The keyboard membrane is more resistant than the original from ZX-Spectrum 48K (very similar to the actual PS2/USB keyboard we use now), and there is also a Sinclair-compatible joystick connector between expansion and mic/ear connectors.

Microdigital TK95Edit

The TK95 microcomputer was the evolution of TK90X made in the 1980s, by Microdigital Eletronica, a company located at São Paulo, Brazil that manufactured some ZX81 clones before (TK82, TK82C, TK83 and TK85) and a ZX80 clone (TK80). The first version was launched in November 1986. This "evolution" was mostly "cosmetic" at the keyboard and whole ABS plastic case. The board is exactly the same as the TK90X and its 16 KB ROM has only minor differences.

Soviet/RussianEdit

ATMEdit

ATM (ATM Turbo) was developed in Moscow, in 1991, by two firms, MicroArt and ATM. It has Z80 at 7 MHz, 1024 KB RAM, 128 KB ROM, AY-8910 (two ones in upgraded models), 8-bit DAC, 8-bit 8-channel ADC, RS-232, Centronics, Beta Disk Interface, IDE interface, AT/XT keyboard, text mode (80×25, 16 possible colours, 8×8 pattern), and three graphics modes.

BalticaEdit

A Russian clone of the 48K ZX Spectrum. ULA replacement made with K556PT4 and K155PE3. CPU running at a higher frequency (4 MHz) which made it less compatible.

Best IIIEdit

A ZX Spectrum clone made in St. Petersburg, Russia in 1993. The size of the system unit is 16.8 × 10 × 2½ inches. It even uses a Russian Z80 clone as CPU.

Bi Am ZX-Spectrum 48/64 and 128Edit

A Russian clone of the ZX Spectrum. The name of the Bi Am ZX-Spectrum 48/64 suggests that it comes with 64 KB RAM. The size of the system unit is 10 × 8.4 × 2 inches. Made of metal. Has the sign Made in RF (Russian Federation) at the back. It was produced in 1992–1994.

The Bi Am ZX-Spectrum 128 was a 128 KB version of the same computer.

BlicEdit

Blic is a domestic clone of the ZX Spectrum 48K. Designed in 1990 on the basis of Leningrad. The board is redistributed, some changes are made. On the board there is an inscription "(C) Blic 1990 Personal computer". When turned on, I displayed the inscription “BLIC” home computer with three rectangles of blue, red and green colors in it.

The firmware contained a modified font of the Latin and Cyrillic alphabet. Keyboard languages were switched to Cyrillic and Latin using the POKE 23607.56 and POKE 23607.56 commands, respectively. The layout of the Cyrillic keyboard is YAVERTA (see photo below).

Hardware implemented the connection to the TV through a high-frequency antenna input, but only in black and white. For the color image, the standard connection for separate Soviet ZX Spectrum clones was used to connect separate RGB color channels and a sync pulse.

The keyboard is rubber, the location and size of the keys is almost identical to those on the original English ZX Spectrum 48K. Блиц — SpeccyWiki

CompositeEdit

A Russian clone of the ZX Spectrum with 48 KB RAM.HCM: The Home Computer Museum .... It is a modified version of Leningrad 2, produced by co-op Composite.

Dubna 48KEdit

A Soviet clone of the ZX Spectrum home computer. It was based on an analogue of the Zilog Z80 microprocessor. Its name comes from Dubna, a town near Moscow where it was produced, and "48K" stands for 48 KBs of RAM.

Ella RaEdit

Also known as the Elara-Disk 128 was a Russian clone of the 128K ZX Spectrum with 58-key keyboard, disk drive, kempston and sinclair joystick. It is possible to expand it, but it's slightly incompatible due to some ports being changed.Sinclair Nostalgia Products - Sinclair ClonesPlanet Sinclair: Computers: Clones and variants: Russian clones

GrandRomMaxEdit

A Russian clone of the ZX Spectrum made in 1993 in Moscow. It is very similar to the Pentagon but INT is re-made to be like the original. There exists four or five models of it but there are only minor differences between them, for instance one has wrong released turbo Beta Disk interface so when you read/write disks on your own GRM everything is normal, but when you want to save something to this disk on any other machine then all information on disk will be destroyed. They are not easy to expand because of some PLM (small ones) chips inside which do not allow you take some signals you may need to attach modem, etc.

The GRM2+ board was used to create the GrandBoard2+

Grandboard 2+Edit

Users liked to plug in two 8-bit DACs to play 4-channel modules of Scream Tracker.

It was possible to run CP/M and a graphics mode with 512x240 pixels was added to be able to run 80 characters per row. It has both parallel and serial ports, sound processor and the possibility to use an IBM keyboard. In later issues it also had a hard disk interface and turbo mode.

RobikEdit

A ZX Spectrum clone produced between 1989 and 1994, by Selto-Rotor (Scientifically technical industrial creative association) a former military factory.

Santaka 002Edit

A clone of ZX Spectrum Plus produced in 1990 in Lithuania. It has Russian symbols instead of lower case English and is reported to be a good and reliable machine because it was produced by ex-military plants as a part of conversion program.

Scorpion ZS-256Edit

Scorpion (Russian: Скорпион), was a very widespread ZX Spectrum clone produced in St. Petersburg, Russia by Sergey Zonov. It had a Z80 processor and from 256 to 1024 KB memory, the Shadow Service Monitor (debugger) in the basic ROM activated by pressing the Magic Button (NMI), a ProfROM with additional included ZX-Word editor, a clock, HDD utilities and more. Various extensions were produced, including SMUC — adapter of IDE and ISA slots, which allowed the use of IBM PC compatible hard drives and extension cards.

Sever (North) 48/002Edit

A Russian clone of the ZX Spectrum. It was made in 1990 and comes with 64 KB RAM and 16 KB ROM. The size of the system unit is 12x8x2½ inches, the weight is 1.5 kg.[7]

Sintez and -Sintez-Edit

A Soviet clone of the ZX Spectrum developed in the "Signal" factory within the Moldovan SSR in 1989.

The original Sintez resembled the "Spectrum +" model, while the -Sintez- was an improved version with a more common mechanical keyboard, an added serial port, as well as the ability for an 8080 or related processor (for example 8255) to be added and used together with the UA 880.

While it was software compatible with ZX Spectrum 48K and has two Interface 2 joystick ports, its hardware was quite different, utilizing different memory chip set-up, lacking slowdown when accessing certain areas of memory, as in original ZX Spectrum, so, certain applications and games may not behave correctly or crash.

Spektr 48Edit

A Russian clone of the 48K ZX Spectrum. It used a membrane keyboard and has both Latin and Cyrillic letters. It was made in 1991, by Oryol PC manufacturer, a former military factory. The ROM includes a monitor program.

OtherEdit

AZX-MonstrumEdit

A proposal for a vastly modernised ZX Spectrum compatible computer. The CPU is Zilog Z380 (a 32-bit version of the Z80, capable of running at 40 MHz), it has its own graphic adapter, AT-keyboard, own BIOS and extended BASIC-ROM, and RAM expandable up to 4GB linear. The computer is supposed to be almost 100% compatible. Standard devices of are HDD-controller, DMA vs IRQ controller, ROM-Task Switching and more. So far only the HDD-controller is produced but the rest exists as drawings. All the plans are freely available.

Elwro 800 JuniorEdit

 
Elwro 800 Junior system
 
Elwro 804 Junior PC

Polish clones of the ZX Spectrum. It had a full size keyboard and even a paper holder. The reason it has a paper holder is that the case was originally designed for a small electric organ. A disk drive was available and there also was a version of CP/M called CP\J for this machine. The updated 804 Junior PC had an internal 3.5" diskdrive.

In Poland the computer that won a contest for being the school computer - "Elwro 800 Junior" used DIN connectors for monitor output, cassette adapter, and Junet. Junet had two inputs - in and out (like MIDI). Student computers connected by DIN cables to the teacher's computer, which had the costly floppy drive and printer. Other uses of Junet were for sending messages, or to allow the teacher to see what students are doing on their screens, at the teacher's computer. The computer had also optional Spectrum net, but it was simple jack input/output. To send data the user had to do SAVE on cassette in Spectrum mode, and input had to be connected to Timex/Spectrum. Other ports used D-subminiature connectors, for RGB video, joystick, printer, and floppy drive.[8]

HarlequinEdit

A UK clone of the 48K ZX Spectrum, designed and developed by Chris Smith to aid the reverse engineering of the ZX Spectrum custom ULA chip, and its research documentation. Complete in 2008, it is the first 100% timing compatible clone. Until 2012/13 the Harlequin existed only as a breadboard prototype, but recently, José Leandro Martínez, Ingo Truppel and others produced a limited number of PCB versions (documented here) as an exact board replacement for an actual ZX Spectrum.

HT 3080CEdit

A Hungarian ZX Spectrum clone made by Híradástechnikai Szövetkezet, released in 1986. It was the third computer from the company. The two first computers HT 1080Z and HT 2080Z were clones of TRS-80 and were unsuccessful because of the poor graphics features and high price. They were both school computers. In 1986, in Hungary the school computers have to fulfill new requirements: they have to produce high resolution graphics and support the special Hungarian characters. That's why the HT 3080C came out and it was both compatible with the previous HT machines as well as the ZX Spectrum. You could switch between TRS-80 and ZX Spectrum mode. It had a graphics resolution of 256x192 (standard Speccy) and an AY-chip for sound (to be compatible with the previous HT machines, not with the 128K Spectrum). ROM: 32 KB (Speccy+HT ROMs), RAM: 64 KB (possibly also a requirement for Hungarian school computers, because all school computers in Hungary had 64 KB). It had a Commodore serial port so you could also connect peripherals made for the C64 to it, for instance the 1541 disk drive.

Developed by Jan Kučera aka LMN128, in 2020, it was the first (and still the only one in 2021) clone with 100% hardware and display timings aligned with a digital video and sound output. The machine combines 48K, 128K, +2, +2A and three Pentagon memory models (incl. the latest ROM and 1024 RAM expansion). It has a real 20 Mhz CPU and its FPGA chip combines all the most popular interfaces, like K-Mouse, TurboSound FM, DivMMC, 512*192 graphics modes, ULA+ and many others. It works with the esxDOS, which allows to run all east-european software in TRD and SCL formats.
