FSIO General I/O board has been designed to allow interfacing inputs and outputs to the simulator hardware.
Inputs
There are 4 input 74LS165 ICs providing total total of 32 inputs available on the board. Input devices (buttons, switches, encoders etc.) can be connected to the board with the use of IDC-10 connectors. Each single IDC-10 socket is connected to 8 inputs on a single chip providing: IC1_OUT – inputs 0 to 7, IC2_OUT – inputs 8-15, IC3_OUT – inputs 16-23 and IC4_OUT – inputs 24-31.
REMARK:
Although socket names shows _OUT in the name on the silkscreen layer, these are INPUTS and no OUTPUTS here. Descriptions will be corrected to _IN in a future release.
