MACHINE REFERENCE

InterCompex Hobbit

The InterCompex Hobbit was a Soviet ZX Spectrum “super-clone” built in Leningrad by Michail Osetinskij and Dmitri Michailov, adding CP/M, FORTH, LOGO and a dual Cyrillic/Latin keyboard on top of full Spectrum software compatibility — and, briefly between 1990 and 1992, it was sold in the UK.

Why it matters

The Hobbit was one of the few Eastern Bloc computers to attempt a genuine commercial export into the West as the Cold War ended, built with real engineering ambition — twin floppy drives, classroom networking, three separate operating environments — rather than as a bare-bones clone, only to be undone by mundane problems: a reported UK electrical safety failure and Sinclair’s copyrighted ROM code, by then owned by Amstrad.

What to check before you buy

  • Confirm which of the three Hobbit variants you’re looking at: the original full-keyboard Hobbit with floppy support, the keyboard-less Hobbit console (IA), or the integrated-keyboard Programmable Console Hobbit (PIA) from 1992 — they’re frequently confused online and have different capabilities.
  • Check the keyboard connection carefully — it’s wired to the mainboard with thin, individually soldered wires rather than a ribbon cable, and is a common point of damage.
  • Verify the ROM configuration, since surviving units vary in which operating environments (Beta/CP/M, FORTH, LOGO) are actually fitted in the ROM sockets.
  • Expect to source parts, documentation and even basic identification help primarily from Russian-language collector communities — English-language information is thin and sometimes contradictory.

Audio

Unknown

Storage

Cassette I/O as standard; twin 5.25-inch floppy drives supplied with each unit, expandable to four SS/DD or DS/DD drives; hard disk supported via a patched disk operating system

Ports

System bus, Centronics parallel port, RS232 serial port, three joystick ports (two Sinclair-compatible, one Kempston-compatible)

OS

Sinclair BASIC (Spectrum-compatible), Beta (a Soviet CP/M clone), LOGO, and ROM-socket support for Pascal, Forth and C

PSU

Independent 5V at 1.5A, 220-240V 50/60Hz mains input, 7.5W consumption

Units sold

Over 15,000 produced by September 1990 (InterCompex’s own claim, reported in Your Sinclair – single-sourced, unconfirmed independently)

Successors

None – the Hobbit console (IA) and Programmable Console Hobbit (PIA) were cheaper, keyboard-reduced contemporaneous variants rather than successors

  • Reported UK mains safety failure
    InterCompex's own account was that the machine's mains cable failed a UK electrical safety test during the 1990-1992 export attempt; no specific British Standard or testing body was ever named in any account found.
  • Fragile hand-wired keyboard connection
    The keyboard connects to the mainboard via a series of thin, individually soldered wires rather than a ribbon cable on at least the later Hobbit variants – a fragile joint and a delicate repair on any surviving unit.

  • 1990 Designed in Leningrad by Michail Osetinskij and Dmitri Michailov; over 15,000 units reportedly already produced for Soviet schools by the time it was first shown to the UK press in September
  • 1990 Keith Pomfret covers the machine for Your Sinclair's "Rage Hard!" column, then visits InterCompex's Leningrad offices in early 1991 for a follow-up
  • 1992 UK export retail launch reviewed in Sinclair User (Issue 126, August), priced at £79 through distributor Intercompex-ADB
  • 1993 UK export withdrawn amid a reported electrical safety failure and Amstrad's Sinclair ROM copyright claim; Soviet domestic production had already wound down as the USSR dissolved
