The reason it went into hopper empty is because of dip sw settings.
I seem to recall that some of these old boards had an inversion of switch settings on one package. The only way to know for sure what is going on with the dip switches is to place the board into I/O test.
for that you need to press and hold TEST (or is it books) and apply power.
one of those will tell you how the board "sees" the dip sw.
