Thanks for advice, hope it goes to rev-ed site as update in case others don't see your thread here. Regards
I have made a note of the update.
On the subject of connections etc. I didn't find the micro-USB socket particularly fragile and I am always scared of breaking small connectors off. I think the main thing - and I'm not suggesting anyone has been - is to not be ham-fisted, and don't try and force it if there is an issue; check what that problem may be rather than forcing it. I held the socket and PCB while inserting cable. And don't forget to check it's the right way round and it's the right type of connector.
A trip to Poundland found solutions for not having any micro-USB cables. They sell a "USB Charging Cable" pack of three short (2") USB-A to iPhone, mini-USB and micro-USB cables and the latter is handy to save re-plugging the micro-USB too frequently.
Their "2m sync and charge cable for Kindle and Tablet" and 1m "Micro USB Data/Charging Cable" both work well.
I expect similar can be found at other low-cost discount stores.
Best of all I found a "Docking Station for Blackberry, Nokia, Sony, Samsung" which has a micro-USB connector on a base with a USB-A cable. I am hoping to be able to fit the PCB Scope board inside that and use the raised-up sections to mount BNC through-panel connectors on so I can use it as a more traditional scope rather than plugged into breadboard. I was going to use an old 3.5" floppy disk drive case but this is more compact. Lead fishing weights glued in the base should help keep it place. It's snap apart, no screws, and the wires go straight to the micro-USB so no excess bulk of a traditional cable plug -

Carefully check what's in the box because not all of the range has a micro-USB connector and it's not easy to tell from the packaging.
