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. It had 64 KB RAM and extra circuitry which provided CP/M support, if the Interface 1 extension was also present. The HC 91 had a modified keyboard with 50 keys instead of 40. The HC 90 had a redesigned circuit board supporting fewer, larger memory chips it was functionally equivalent with the HC 85.
It was functionally similar to the ZX Interface 1, but instead of Microdrives it supported single-density or double-density floppy disks. It was used in schools/universities and as a personal computer.Īn optional Interface 1 extension was available for the HC 85, HC 90, and HC 91.

The earliest version, HC 85, closely resembled the Spectrum, with a built-in BASIC interpreter, Z80A processor, 48 KB RAM, tape, and TV interfaces. The designation HC means Home Computer, and for the first three models in the series, the number is the year of first manufacture.

Felix HC seriesĪ series of ZX Spectrum clones was manufactured in Romania from 1985 to 1994, by ICE Felix. The power supply is the size and weight of a couple of bricks including a huge transformer unlike the now-standard switching power supply. Only one set of 8× 1-bit 64 KB RAMs present. The ROM is original Sinclair, although instead of the Sinclair copyright message, it states 'BASIC S'. A nicely built PCB with 45 chips (most 74-family) inside. The keyboard looks nice, but the key switches are very simple and therefore so is the 'feeling'. It is called 'Calculator pentru Instruire Personală' which means 'computer for personal teaching'. CIP-03Ī Romanian ZX Spectrum clone made by Intreprinderea Electronica. Romanian CobraĪ ZX Spectrum clone built in Braşov, Romania.

An article on how to build a Mistrum was published in the Czechoslovak amateur radio magazine Amatérské Radio nr 1/89. As the Mistum was a hardware design they may look very different as each builder made his own case and keyboard. The ROM include Roman chars and Roman chars with Czech diacritic marks. MistrumĪ Czech clone of the 48K ZX Spectrum. ULA designed from discrete 74xx ICs, screen part or RAM was synchronized perfectly, without CPU blocking. KrišpínĪ Czechoslovakian clone of ZX Spectrum, developed by František Kubiš at 1984, student of EF SVŠT (Electrotechnical Faculty of Slovak Technical University) Bratislava. Last ZX spectrum compatible model was Didaktik Kompakt (1991) which has integrated 3,5 Floppy disk mechanic and sound chipAY-3–8920 and still 48KB of RAM.
Gama-series was soon followed by the Didaktik M (first variant released at 1990 second variant release at 1991), M contain much better keyboard and Sinclair and Kempston Joystick ports.
Didaktik Gama has 80KB RAM comparing to original ZX spectrum. There were three main models of Didaktik ZX clones: First was Didaktik Gama (released in three variants 87, 88 and 89). Later models compatible with ZX Spectrum were based on the U880 and Zilog Z80 processors. The Didaktik was a series of home computers produced in Skalica, former Czechoslovakia, now Slovakia.
