IEEE Port
LED 1, TALK, flashes whenever the IEEE port of the PSI
BOX sends a byte down the IEEE bus. LED 2, LISTEN, flashes
whenever the IEEE port of the PSI BOX accepts a byte from the
IEEE bus, the byte is stored in the PSI BOX internal buffer.

The IEEE DIP Switches.
DIP switches 1-5 on switch block 1, in conjunction with
the MODE switch 7 & 8, are used to set the all the IEEE
options. These options include IEEE address, IEEE controller
mode and source of the IEEE data.

The DIP switches are only read when the PSI BOX is
powered up. Changing the DIP switch setting whilst the PSI
BOX is running will have no effect.
