TS-8150-PC104

From Technologic Systems Manuals

The PC-104 connector consists of two rows of pins labeled A and B, the numbering of of which is shown below. The signals for the PC-104 are generated by the MAX240 PLD located on the baseboard. It converts the MUXBUS signals from the dual 100-pin Macrocontroller interface bus. Pin A1 is nearest to the macrocontroller mounting hole.

Any of the IO on this board labelled DIO_ can be controlled through tsctl as PC104_A/B<pin>, or through manipulation of the registers directly.

You can also drive these DIO to manually manipulate the PC104 address to make peripherals usable that require a higher range of address than provided by the default address space of the MUXBUS.
