Talking of old kit
My memory has been jogged - someone made a business of using old kit years ago.
In the 1970s I worked for a company who used both analogue and digital technologies. As we moved over to digital the analogue machines were retired but the companies who bought our (geophysical) data sometimes wanted it reprocessed using the latest techniques. Of course, they had the original analogue recordings which we could no longer read, having disposed of the old equipment. The recordings were on magnetic tape and some were in a strange format, like 6-inches wide and a yard long. We had to send them to another company who must have bought many of the obsolete machines knowing there would be a market for these conversions of old media to digital.
