PAL and SECAM are color encoding schemes, they are completely different. They will of
course display black and white if you use one on the other and vice versa. The same is
true if you also use an NTSC TV to display PAL (sync rates aside, usually that can be
tuned with a V-hold adjustment or automatically by the set).

Bulgaria in those days wouldn't have been PAL. They would have been
using SECAM.
Though isn't SECAM essentially PAL but with the colour encoded slightly differently.
e.g. if you feed a SECAM signal to a PAL display you get a picture that is black and
white.
