I just scanned the PDP11/23 and 11/34 pocket guides and posted them in GIF format at ftp://zane.brouhaha.com/pub/dan/pdp1134 and ftp://zane.brouhaha.com/pub/dan/pdp1124 In ftp://zane.brouhaha.com/pub/dan/ you will also find the TD systems Viking user and technical manuals that I OCR'd but the OCR did not do a good job of keeping the tables lined up. There are a few GIF's of those important pages. There is a UDT and a QDT jpg of the boards also. These boards have been very commonly rebadged with other companies names on them. They are Qbuss and Unibuss SCSI disk / tape controllers. Mixed in are UC0* files (GIF's) that are the important pages from the Emulex UC07/08 Qbus SCSI manual to set them up also. Zane hopefully will sort them into their own directories and post the new directory info. Dan
