These were intended for professional users -- monitor, printer, hard disk drive (in model 1841), development kit and productivity software were included.

	Models 1840 and 1841 mimic IBM PC 5150 and IBM PC XT 5160, but are not 100% compatible -- some features are missing (no support for 8087 math co-processor in the 1840), some hardware is completely (serial port) or partially (keyboard scan codes) incompatible. The bus is ISA, cards use a different form factor (20x24 cm with a single 135-pin connector). Video adapters are extended versions of MDA and CGA (both support downloadable text-mode fonts). Model 1841 could route sound from optional speech synthesis board to internal speaker and supported a bus mouse.

	1840 and 1841 shipped with customized versions (likely not authorized by original developers) of operating systems and application software -- CP/M-86, MS-DOS 3, SuperCalc, WordStar etc. CP/M and DOS were fully translated to Russian, down to command names. The hardware and BIOS is compatible enough that unmodified software will also run.		1840 and 1841 shipped with customized versions (likely not authorized by original developers) of operating systems and application software -- CP/M-86, MS-DOS 3, SuperCalc, WordStar etc. CP/M and DOS were fully translated to Russian, down to command names.

	Since the hardware is so different from the original PC (DMA controller is missing, video hardware is somewhat CGA-compatible but has no mc6845 or native text mode, and so on), some software (mostly games) was patched to run on the Poisk.
