PDP-11/53+ Jumpers (scanned manual)

Many thanks to Antonio Carlini and Kees Stravers for making the manual available. I glanced through it. It turns out this manual is for the 11/23. It has a lot of very useful info for the KDF11-BE (M8189, the quad-wide 11/23 CPU) -- jumpers, bootstrap options, etc., plus info on the RQDX1, BA23, XXDP, and more. There's also an 11/84 manual at the same site. Now if we could only find this sort of info for the 11/53. These two manuals may help some by giving us a feel for what kind of things DEC uses jumpers for on CPU boards. Now that we know what to look for, maybe we can figure out some of the 11/53 jumpers by experimentation. Kees -- I suggest putting a note on that entry so people websearching for 11/23 or M8189 info can find it more easily. -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 24800 Tungsten Road Advanced Technology Euclid, OH 44117 USA Euclid Labs http://users.safeaccess.com/engdahl ----- Original Message ----- From: <kees.stravers(a)iae.nlindex from http://vaxarchive.khubla.com/manuals/
