Anyone else have much experience with the DOS-73 board? ?
Hi,
I used the DOS-73 board as a true coprocessor board. It produced an inset DOS window when running. As I recall, it had complete access to the system hardware (HD, floppy, communications). It shared the busses. You could resize the DOS window, in the
same way that you could resize any other window. It would run anything that would run on a monochrome monitor. It seems like there was an 8087 chip onboard as well. It was virtually equivalent to having a DOS computer of that era, side-by-side with a
UNIX computer.
