British DRI 8 inch floppy drives (Data Recording Instrument Company Limited) doco sought

[exidyboy]

I would like to get a pair of Model 7200 DRI 8 inch floppy drives going for an Exidy Sorcerer connected via a Digitrio controller board inside their enclosure. The manufacturer is an apparently a British company called DRI or Data Recording Instrument Company Limited according to the specification plate. The only search hits I have so far are to patents and mentions in Hansard.

Would be looking for technical literature, service info, schematics etc.

Thanks,

Michael
