"ector Graphic BitSt:reamer II Board
If you install a 1488 driver in socket U25 or U28, then the funct ions of
the various jumper pads are described in Table 7. Analogously, if you
install a 1489 receiver in socket U25 or U28, then the functions of the
various jumper pads are also described in Table 7. "C,E-n" means pad n of
either .;rea C or f\!"ea E, depending on whether you are using socket U25 or
U28. The saTIe is true for l1D,F-n". If two pads are listed for a function,
they must be jumpered together and then jumpered to the input source. (Such
a circuit will not accept an input unless it appears on both pads
simultaneously.) Connect the pads requiring voltage and ground to the
voltage and ground jumper areas on the board, found just below Areas E and
F.
