More Sinclair clones were produced
in the former Soviet Union than in the rest of the world put
together. Although clones were manufactured in several of
the former Soviet republics, the Russians were by far the
largest users and developers of cloned Sinclair computers.
In many cases, the machines were designed and built by electronics
enthusiasts reverse-engineering smuggled-in computers. A complicating
factor for the Russians was the difference in alphabets; consequently,
many Russian Sinclair clones were built with support for both
Roman and Cyrillic characters. Many Russians are still, to
this day, keen Sinclair users, although inevitably the PC
is becoming predominant.

Notes
|
Baltic
(aka Baltica)
|
|
1988
|
Spectrum
clone built using a Soviet-developed K556PT4 or K155PE3
processor running at 4MHz instead of the 3.54 MHz Z80A
used in the real Spectrum. This made it slightly incompatible
with the Spectrum. Produced in the Baltic States, hence
the name. |
Delta
|
|
1991
|
Generic clone based on the Spectrum+
with virtually identical specifications (the only major
addition being Sinclair and Kempston-compatible joystick
ports). Produced at Zelenograd, near Moscow.
|
Delta S-128
|
|
1990
|
ZX
Spectrum clone with considerably different
hardware spec. Uses a 7MHz processor. Also includes
built-in Kempston and Sinclair joystick interfaces ports,
TV and RGB monitor output, printer interface, sound
processor and optional disk drive. Produced in Voronezh,
Kazan and other cities. (Also reportedly produced in
Yugoslavia, although this is presently uncorroborated).

Ella Ra
(aka Elara-Disk 128)
|
|
1991
|
Spectrum
128 clone with a floppy disk drive and Kempston
and Sinclair joystick ports; somewhat incompatible with
the original Spectrum.
|
Hobbit
(aka Hobeta or Hobbit Personal
Computer)
|
|
1990
|
A Leningrad-produced
Spectrum
clone with a high degree of compatibility and a considerably
improved spec: 3.5 MHz Z80 CPU, 64Kb RAM, twin 5.25"
disk drives, three joystick ports, TV and RGB output,
parallel and serial ports, support for networking, external
disk drives and hard disks. Many Hobbits were produced
for use in Russian schools. A second version was produced
in 1991 with a 3.5" floppy disk drive in the right-hand
part of the case (like the Amiga). |

Kay 1024
|
|
1998
|
A cross
between a Spectrum
and a modern PC, with 10 MHz CPU, 1Mb RAM and a hard disk
drive. Also has Kempston and Sinclair joystick interfaces,
a printer interface and support for external disk drives. |
Krasnogorsk
|
|
1990
|
Produced
near Moscow, this Spectrum
clone attempted to rectify certain flaws of the earlier
Baltica and Leningrad-1 machines. Unfortunately it was
itself significantly flawed and failed to win much of
a market. |
Kvant-BK

Russian
clone of the Spectrum. |
Kvorum
|
|
?
|
Generic
Spectrum
clone. |
Kvorum-64
|
|
?
|
Basic Spectrum
clone with 64K RAM. |
Kvorum-128
|
|
?
|
More advanced
version of the above with 128K RAM and the ability to
run run CP/M and TR-DOS. |
Kvorum-128+
|
|
?
|
As above,
but with 3.5" floppy disk drive. |
Leningrad-1
|
|
1989
|
A simple
and cheap machine, this Spectrum
clone acquired widespread popularity. Not very Spectrum-compatible,
due to the way the machine was designed. |
Leningrad-2
|
|
1991
|
A much improved
version of the above with built-in Kempston joystick compatibility. |
Magic |

Russian
clone of the Spectrum. |
Master
|
|
1990
|
Generic
Spectrum
clone with hardware spec close to the original: 48Kb RAM,
16Kb ROM and built-in Kempston joystick interface. |
Master K11
|
|
1991
|
A generic
Spectrum
clone from Ivanovo, east of Moscow. May be a later version
of the Master. |
MC-64
|

|
1993
|
Spectrum
clone with 64Mb RAM, made by Peters
Plus of Russia. |
Mistrum
|
|
1989?
|
Generic Spectrum
clone, available as a build-it-yourself hardware design.
For this reason, assembled Mistrums have a wide variety
of external appearances, depending on what cases have
been used.
|
Moskva
|
|
1988
|
Generic
Spectrum
clone. A highly popular machine mass-produced for the
Soviet market. |
Moskva-128
|
|
1989
|
Spectrum
128K clone, with built-in printer and joystick
interfaces, TV / RGB monitor output but without a sound
processor or floppy disk drive. |
Nafanja
|
|
1990
|
Generic
Spectrum
clone with built-in joystick port and an ugly round-button
keyboard. Built in a case for ease of transport, it was
apparently designed for the Soviet elite (this is certainly
suggested by the fact that its cost, 650 roubles, represented
more than two and a half months' salary for an ordinary
worker at the time). |
Pentagon-48
|
|
1989
|
Generic
Spectrum
clone, similar to the Moskva, but without RGB output and
with a better speaker. |
Pentagon-128
|
|
1989
|
Spectrum
128K clone, similar to the Moskva-128. Like
the Mistrum, it is not a brand name but a hardware design
to be assembled by the individual user; this means that
individual machines can look and be considerably different.
The current standard configuration is a Pentagon 512 Turbo,
with 512Kb RAM, two floppy disk drives and a Kempston
mouse. |
Robik
|
|
1991
|
Fairly standard
Spectrum
clone with a built-in Kempston joystick port and output
to RGB, Hercules or EGA monitors as well as the ability
to switch between Latin and Russian fonts. |
Santaka 002
|
|
1990
|
Clone of the Spectrum
produced by military plants as part of a conversion
process (swords into Spectrums?), and consequently rated
rather more reliable than most clones.
|
Scorpion ZS-256
|
|
1992 to present
|
Considerably developed Spectrum
clone using a Z80B 7Mhz CPU with 256K RAM, giving it
fair compatibility with a Spectrum 128. It comes with
serial and parallel ports, a disk drive controller and
TR-DOS. The machine is still being developed in Russia.

Sever (Nord) 48/002
|
|
1990
|
Generic
Spectrum
clone with 64Kb RAM and 16Kb ROM. |
Sintez 2
|
|
1993
|
A Moldovan-produced
copy of the Spectrum+,
with TV and monitor output and built-in joystick ports. |
Spektr 48
|
(Larger
image - 57Kb)
|
1990
|
Generic
Spectrum
clone with Roman and Cyrillic font switchability. The
machine uses a locally-developed KP580-80A as its CPU,
in place of the original Z80. In a retrograde step, it
has a ZX81-style flat membrane keyboard in place of the
more usual PC-style keyboard found on Russian Spectrum
clones. |
Sprinter
|
|
1996
|
Easily the most radically developed
clone, barely recognisable as a Spectrum.
Has a Z84C15 CPU running at 28MHz (switchable to 3.5MHz
for backwards compatibility), 4Mb RAM and a 128K ROM.
Storage is provided by a 3.5" or 5.25" floppy
disk drive and a hard disk controller is provided. Two
serial and parallel ports are provided, along with two
ISA-standard expansion slots. AY-3-8910 or COVOX sound
chips produce sound. The machine generates up to 16m
colours, of which 512 can be on screen at once in 640x256
resolution. TR-DOS and MS-DOS are supported.
|
ZX Next
|
|
?
|
Spectrum
clone (apparently also marketed as "ZX Frium 2"),
capable of operating in PC-standard 640x200 (CGA) mode.
Unusually, it used two Z80 CPUs - the extra one was
used as a video controller.
|
ZX-Profi
|
|
1990
|
Somewhat modified clone of the Spectrum
with 1Mb RAM and added CP/M mode. It also had parallel
and serial ports, a sound processor, a hard disk interface
and a "turbo mode".
|
"ZX Spectrum"
|
|
1990s
|
Several
clones of the ZX
Spectrum were produced and distributed under
the same name as the UK original, or under no apparent
name at all. They appear to have shared very similar specifications. |
