Well from what Pete's said the Tube ULA at least is already well
documented - so at least some replacement can be made when the proper
ULA gets too scarce.

Most of the schools in the UK seem to have cleared their older Acorn
machines out in the last three years or so, so there probably aren't
*that* many to be found in the wild any more (relatively speaking) -
most of them are probably now already in the hands of the people who
want to keep them.
