The Sanyo MBC-4000 series succeeded to the [MBC-1150](/museum/sanyo-mbc-1100-1150/). It was the same all-in-one system including one (MBC-4000) or two (MBC-4050) 5.25" floppy drives, a monochrome display and a very complete keyboard.

It featured a true 16-bit Intel 8086 CPU and shipped with the CP/M-86 operating system as well as a Basic interpreter and a spreadsheet called Goal.\
MS-DOS 2.11 was also available on this machine.
