BDOS is a CP/M term.  On the PC under MS-DOS, there are three ways to
write to the screen: MS-DOS calls, ROM BIOS calls, and direct MOVs to
the regen buffers.  Also, a program may work only with the monochrome
display or only with the color/graphics display.

If you have the source code, converting to the Godbout MP/M system
would require changing the program's video I/O to conform with
whatever that system requires.  If you don't have source code, the
only hope is to make the target system look like a PC, perhaps by
installing an IBM display driver card and providing DOS and BIOS calls
functionally compatible with the PC.
