This archive contents a description to built a parallelport test
adaptor and two programmes to control the bits at this port.
(Only amiga internal parallelport.)

The hardware checks the lines and indicates a dataflow over the
port.
(All parallelports e.g. of I/O-cards or other [non-amiga] pc's.)

With one programme you are able to set and clear all databits
and the signals Bsy, POut and Sel additional (testing the port).

The other programme is only to set and clear the databits.
This is usefull to control a connected relay-card.

In both programmes you can switch the power-led high and low
(this switches also the audio filter in most amiga models).
