• BK-0011M: with MSTD or KNGMD

Emulated Hardware:

• Processor K1801VM1 (basic set of commands, except those specific to HALT-mode)
• Video controller K1801VP1-037 (color and black-and-white modes, screen palettes)
• Keyboard controller K1801VP1-014
• Built-in timer K1801BE1

• 11M system timer (50 Hz vector 100 interrupt, bit 14 in register 01776662)
• Page memory 11M (bits 8-10, 12-14 in register 01777716)
• Standard six-button joystick on the parallel port
• Drive controller on flexible magnetic disks K1801VP1-128 (KNGMD, "read-only" mode)

Supported formats:

The emulator supports loading and saving program images in KUVT-86 (.BIN) format by intercepting EMT 36 on the BK-0010 or system call .BMB10 on the BK-0011M format, as well as mounting images of floppy magnetic disks in the .IMG/.BKD (800 KB) format.
