=== CPC6128 machines with MX4 backplane===
The 6128 expansion port adapter requires a 50 way right angled male IDC box connector fitted to the expansion port adapter. This allows it to stand up on the MX4 backplane. The main caveat is that the adapter is inserted the other way round to the other MX4 boards, so some rearrangement of your MX4 boards may be necessary.
