The Centre for Computing History at Cambridge, UK have have a UDR700 https://www.computinghistory.org.uk/det/16227/Ferranti-Paper-Tape-Reader/ and interface drawings for a Ferranti FM1600B; I believe they also have the machine : all extracted from HMS Dryad in the 90's IIRC. With notice they can provide access to the paperware (for the interfaces) - I have photographed the ccts. However, it has been through technical writers and I could find no insightful prose. I doubt what I have adds to Tony's UDR700 manual and your Argus knowledge.

I've already identified some dried out capacitors in my readers, once they have been replaced I can use the manual to go through the setup procedures. Thanks for the offer of the HSR500 manual but I already have an electronic copy of it, I think from Bitsavers. I have been able to compress your manual down to under 8Mb using a free trial of an online Adobe utility. https://www.adobe.com/uk/acrobat/online/compress-pdf.html Thanks once again for your help. As an aside, I saw in the conversation thatsomeone thought the UDR700 was used on the Ferranti FM1600B. When I was a Ferranti apprentice in the early 1970s I worked in the FM1600B commissioning area in Doncastle Road Bracknell. The only reader used then was a rebadged ICL TRM 1000. With this reader you really did have to aim the tape into the collection basket!!
