Fail to build due to the absence of video.[ch]

[jserv]

I managed to build this project under Ubuntu Linux. However, it failed because there is no required video.h. GCC complained below:

emulator.h:7:10: fatal error: video.h: No such file or directory
    7 | #include "video.h"
      |          ^~~~~~~~~
compilation terminated.
make: *** [Makefile:17: emulator.o] Error 1

Also, I have to apply the following changes:
