It is a UDR 700, my dyslexia and why I did not find your posts from 2020. A copy of the user manual would be very much apreciated, as would info on the unibus interface. However, I'm quite happy to interface to the back of the reader "I think". I shall eMail you privately details of an FTP site you could upload to. Martin

The latter is a 'UniDirectional Reader' running at 700 characters/second. I've seen them badge-engeered 'Solartron' too. I also have a Unibus interface for them. If it is a UDR700, I have the 'user' manual which includes full schematics, parts lists, alignment data, etc. I did offer this to bitsavers along with the manual for the HSR500 (bidirectional, 500 cps) but they weren't interested. Unfortunately the manual is nearly 140MBytes (my scanner software is very inefficient!) so too large to post or e-mail, but I can snail-mail a CD-ROM or memory stick with it on. -tony
