Hi Sid

That looks a very significant step towards 'reminding yourself how you had
used the 4/40 back in the 1970s. It shows how well the hardware has
survived in your custody, as well as the skill and perseverance you have
applied to restoring it.

This is excellent news. We should make arrangements for someone to video
your machine in operation - to stand alongside the rather few examples of
other Intellecs on YouTube.

All the best

Jon
