Laserdiscs and Domesday Machines

[ffutures]

I recently updated my eBay UK guide to laserdisc players

and realised that I'd forgotten to say anything about one of the strangest and most ambitious laserdisc systems - the old BBC-based Domesday Machine.

So I've written another guide for that, based on everything I could remember about using the things (which turned out to be less than I thought); unfortunately eBay won't allow external links and I didn't want to strip mine other sites for details, so it's ended up a bit brief. In particular, I find I can remember virtually nothing about the RM Nimbus-based version, which generally seems to get little coverage. Anyone able to suggest anything I should add?
