When using the header strips to provide the bus interface observe the following:
• All I/O signals on the ISA bus card edge must be isolated from the ISA bus (do not plug the card
• For the ISA bus, a 22V10 PAL (U4, socketed) is currently used to provide the S1D13505
into a computer). Voltage lines are provided on the header strips.
CS# (pin 4), M/R# (pin 5) and other decode logic signals. This functionality must now be
provided externally. Remove the PAL from its socket to eliminate conflicts resulting from two
different outputs driving the same input. Refer to Table 2-2 “Host Bus Selection” on page 8 for
connection details.
