Recent Activities (11/34)

This weekend I decided to start the process of building and making work my PDP-11/34 (upgraded to 34a). Most of my CC activity will have to occur on the weekends, because my job is quickly ballooning to nearly fill up each day. Not that I mind; my job is fun. Now before you can get that "I told you so" off your lips, I will have you know that I *still* have more time than when in college for playing with my toys. Weekends are better than nothing. The first thing was to get access to the machine. Ouch, but success. Next, I made an inventory list of all the cards in the machine. I'll paste it at the bottom of this mail. Next, I downloaded and started reading some manuals, including 11/34 UG, BA11-K UG, BA11-K FMPS. There are a lot of pages there, and I want to read them before doing too much more, so I'll print them out and take them to work for some lunchtime entertainment. Another thing I decided was that I needed to mount this thing in a rack before I do too much more with it. Mainly, I need to get to the underside easily. I tried to harvest some rails from the rusty 11/70 carcass in the garage. After some work, I was able to get the BA11-K in the carcass to slide out, but it was too stuck to get off of its rails. I couldn't tilt it up, either, because one of the releases wouldn't budge. I decided to take the entire thing off, rails and all, and remove the rails later. I also decided to get a friend to help, just in case. Unfortunately, my friend is sick this weekend, so I couldn't do much more. I did fire up the compressor and blow air into the machine and into the LA120 I have nearby. I think I'll play with the LA120 a little and see what condition it is in. Next weekend, I hope to get the 11/34 mounted in the H960 rack, read the manuals, and document jumper settings on the various boards.
