Does anyone knows what it would be worth today? (Billings bc-12fd)

I worked with four BC12-FD (until 1985), each had 2 units of 8-inch disk (1MB each disk) in a separate gabinate. Here some very interesting features:
a) the operating system OASIS, was a subset of IBM''s CMS running on Virtual Machines (VM) of the IBM 370. The commands have the same syntax and the same options.
b) the file names were the same as in CMS, "filename (8). extension (8): drive (1)"
c) you could connect two or more networked computers using the RS232 serial output in a ring topology. Making it possible to send files from one computer to another.
d) The BASIC was very structured, with statements like: SELECT-CASE-CEND, IF-THEN-ELSE-IfEnd, WHILE-WEND
e) In addition to driving key indexed files with string
He was an excellent computer for its time (Commodore 64 and Radio Shack).

RE: The Billings Computers were quite astounding for their time. They offered 64K of memory, and dual 360K disk drives (SS/DD) dual 720K diskette drives (DS/DD NOT HD diskettes) in later models. They all ran the OASIS operating system (later renamed THEOS). I still have mine and it runs. I have COBOL, FORTRAN, BASIC, Assembler, plus numerous business applications. Mine is the later model with the "steel case" that replaced the fiberglass case in the photo. The company that produced them was founded by Roger Billings who did significant hydrogen research, as well as early networking of computers. In the sub-directory (/dda) of my web page is some interesting AT$T computer archives.
