The HC-2000 was an upgraded version of the HC-91+. It was also compatible with the Sinclair Spectrum but could run as well the CP/M operating system and all its associated software.
It was actually an HC-91 with internal disk interface and 3.5" floppy disk drive. Major hardware differences were a white larger case housing the floppy drive, and 64 KB of RAM of which 48 KB were available in Spectrum mode, and 56 KB in CP/M mode.
There were two versions of the HC-2000, with or without built-in floppy disk drive.
Two 32 KB ROM chips were used. First one held the Spectrum BASIC, second the CP/M O.S. and IF1 disk interface.
The ROM also held specific commands to manage the diskettes (FORMAT, CAT, LOAD, SAVE, VERIFY, ERASE), as well as a RANDOMIZE USR 14446 which allowed to load the CP/M OS. At boot-up, a simple RUN command loaded and ran a 'Run' program (ancestor of MS-DOS 'Autorun') on the diskette.
The HC-2000 was the last home computer produced by ICE Felix. A business version version was later produced, it had approximately the same case design but featured a 386SX-25 or 33 MHz and built-in 1 MB RAM and VGA interface.
ICE means means Intreprinderea de Calculatoare Electronice (Electronic Computers Factory), and HC meant Home Computer. The company still have a Web site.

Pentru Stefan Marianescu : 1. De ce nu folositi limba romana.? 2.PC 386 a fost realizat in 1993 s-au facut si citeva zeci de bucati.Nu a fost o serie de fabricatie mare datorita lipse linii asamblare componente SMD.Am avut o linie semiautomata in care asamblarea pick and place se facea manual, componenta cu componenta iar echiparea unei placi de baza lua citeva zile. 3.Nu faceti asemenea afirmatii , chiar daca este dreptul dumneacoastra democratic, fara a va informa despre subiect.
