Are you sure it's a UTR700 and not a UDR700? 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
