Interesting. I had a couple of Quad-X systems; one went off to the Centre 
for Computing History when I moved to the US, but the other I parked at 
TNMoC and can hopefully get back at some stage (post-pandemic). I don't 
know how many QX systems were made, but I don't think it was many - and 
they're probably significantly rare in the US.

I do have some Quad-X source/design bits and pieces, I believe - I 
inherited a pile of Torch corporate hardware ~15 years ago, and among that 
were a couple of drives which had come from one of the company servers.
