Finally, after canablising and repairing motherboards of three dead A5000s I now have a working fileserver again! At last I can get on with the important tasks in life - getting set up to run a viewdata BBS up at the Acorn World show up in Huddersfield next month.
There will be intermittant access to it in the run up period; if anybody wants to re-live the glory days of being online in the 1980s, then watch this space for access details.
