"The Sanyo MBC-4000 series succeeded to the MBC-1150. It was the same all-in-one system including one (MBC-4000) or two (MBC-4050) 5.25-inch floppy drives, a monochrome display and a keyboard."
"It featured a 16-bit Intel 8086 CPU, 12K of ROM and 128K of RAM. The MBC-4050 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."
NOTE: The link just above also has manuals and articles for the MBC 4000 series."
The IA upload is by a frequent uploader, he announced these here:

" I bought some terminals from a guy on Facebook marketplace last week and he told me he used to be a Sanyo dealer in the early 1980's. I asked if he had any software and he gave me a few pieces of software for the MBC-4000 series. These are just the system disks (CP/M 86 and MS-DOS) and the Wordstar suite for this specific system. The MS-DOS kit has a character ROM with it that I guess is needed to get MS-DOS running on these systems. I dumped that ROM as well."
