TV noise caused by Miracle Expanderam

Louis, on the sellmyretro.com site has been doing some work on QL hardware.
He has a second hand Miracle Expanderam, which lacks the case, and when connected to his QLs, he found that there was a lot of interference on the TV picture.
To overcome this, he has added a lot of M1 ceramic capacitors to the Miracle board on the solder side. One capacitor to each RAM and one to 74HC245.
This has improved the picture greatly.
