SWRITE <slot><register>,<data>
Writes data to the output port on a 44475A breadboard in the specific
slot. The data value is a decimal sum of the binary weighted values of the
bits that are to be set high (+5 volts).
The slot parameter is a decimal ranging from 0 to 9 (mainframe
dependent). Valid slot numbers are:
Two 8-bit ports are available on the 44475A Breadboard. One port is a
static read only port (04), the second port is static write only (00). Static
means that there is no handshaking involved in data transfers.
The register parameter value is 00. Any number between 1 and 7 may be
used without causing an error, however no action will be taken by the
Breadboard.
data is the binary weighted sum to write to the register. data can range
from 0 to 255.
