The reason for this is because they require loopback cables in order to properly test these functions, and without, there is simply the report of a failure.
The good new is, that such a solution is still available from Olivier at his web site, Gossuin.be.
This is what you get:

So what you see is:
A central loopback testing hub.
A 25 pin serial port test dongle.
A 9 pin serial port test dongle.
2x 9 pin joystick/mouse port testing cables.
An ACSI test cable.
A Centronics/printer test cable.
A Midi test cable.
I also opted to buy a 2nd diagnostic cartridge to make a little kit up, which can be seen on the right.
To follow will be examples of testing using this kit, and showing the results for the standard ST range of machines.
I hope you'll find it useful.
