Having recently joined the group I'm trying to get used to and understand how the forum pages work and I came across the message from Chris M, copied above. I also have a Hornby Zero 1 system with UK 220v input volts. One Master and One Slave and a couple of decoders sitting in two locos. I could retrieve these if there is interest. The units have had minimal use in the UK before I moved to the USA. These would be shipped from Michigan. So this would be the only cost to the interested party.
For anyone interested, MERG sells a keyboard refurbishment kit (currently £10.50), which replaces the rubber membrane, incidentally this also works for the H&M 5000 system as well. Paul
