Recovery adventure - Re: Unidentified DEC gear available, NSW-AU

Well, it started with 'Unidentified DEC gear available, NSW-AU'... A few weeks ago you saw some poor quality photos Jay posted from someone who had found a PDP-11 of some sort. It seems no-one could identify it or the ancillary equipment at the time. As it happened to be located here in Oz, and only in the next state, I thought it was worth a gamble on going to rescue it even though it was hundreds of kays/miles away and would mean a few days driving. So I took last Thursday and Friday off work to drive down in my ute from Brisbane to the gear's location. I drove the inland highway and just camped along the way each evening. The weather was very warm and pleasant. During the evenings the mozzies were out in force, biting. Arriving at the location first thing Saturday morning (as I had camped the second night nearby) I was shown the horse stables where the gear was stored. It was near an entrance and the top of the rack was covered with a tarp. http://www.surfacezero.com/g503/data/4173/gear_recovery_01.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_02.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_03.jpg The rack was sitting directly on the dirt floor. The stables hadn't been used for decades as such and there was a lot of mouse and other animal droppings on everything. The front of the rack was against some horse tying-up posts so we got to work levering it away from them to get to the front, for which I had brought gloves. http://www.surfacezero.com/g503/data/4173/gear_recovery_04.jpg At this point I realised what I was looking at. It was a Foxboro Fox 2 computer, essentially a rebadged PDP-11/20. http://www.surfacezero.com/g503/data/4173/gear_recovery_05.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_06.jpg A while ago I had by chance downloaded and looked at the very same brochure for this machine, I think perhaps because it had been mentioned here. So I was able to identify it immediately. This is that brochure: http://archive.computerhistory.org/resources/text/Foxboro/Foxboro.Fox2-30.1… The cabinet was about two and a half 19" rack-widths wide, painted lime green and with custom industrial control equipment to the left and the computer, paper tape reader and expansion box in the right. The half width section contained a series of power supplies. almost all cables had Winchester MRAC connectors on them (visible in the original photos, and I happened to have a need for some for my Diablos). There were no peripherals of any sort apart from the paper tape reader and the custom A-D I/O. No disc drives nor the fabulous drum shown in the brochure. At the bottom of the computer rack section there was a very sad PDP-11/05, missing its console, and full of mud. Being at the bottom it had been flooded over the years and was silted up. It had a cable to the BA-11 expansion cabinet. http://www.surfacezero.com/g503/data/4173/gear_recovery_07.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_08.jpg I started by removing the 11/05, as there was a (very very) slim chance I might be able to use it for some spares, and I had a need for the BC-5 Power Control Unit in the chassis anyway. This machine was not on rack slides but just lying on the bottom on the dirt. Surprisingly the paper label on the top panel was still partly legible, considering the immersion. http://www.surfacezero.com/g503/data/4173/gear_recovery_12.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_13.jpg Next I worked on removing the BA-11. It was pretty much empty with only a small Unibus backplane. http://www.surfacezero.com/g503/data/4173/gear_recovery_14.jpg After that I attended to the Fox 2, and before long after a lot of sweating we had the machine out and ready to load onto my ute. http://www.surfacezero.com/g503/data/4173/gear_recovery_09.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_10.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_11.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_15.jpg Finally I removed the Foxboro paper tape reader. The tape holders each side slide up to reveal the rack mounting screws. Onto the ute it went. There were some other racks of gear, but all custom idustrial control equipment. One rack had a DEC A-D Converter in it with some serious cables connected to some backplanes of the smaller Flip Chip modules. I grabbed the A-D and Flip Chips. http://www.surfacezero.com/g503/data/4173/gear_recovery_16.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_17.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_18.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_19.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_20.jpg There is an identical DEC A-D on eBay at the moment which shows you what it's like: http://www.ebay.com/itm/Digital-DEC-A-D-Converter-/141324598814 The I/O for the machine was (I believe) an ASR-35 the bigger brother to the ASR-33. I couldn't take it, it was wedged in behind the other racks and I had only a limited amount of time to load the equipment before I had to head back interstate to home. I did not see any sign of the optional I/O Selectrics shown in the brochure, as I would definately have liked to have found those if I could have! I don't think this machine had them, only the ASR-35, as no printout I found appeared to be done by a Selectric. There was a smallish dumb terminal under some junk, this didn't have any brand or logo on it. Can anyone identify it perhaps? http://www.surfacezero.com/g503/data/4173/gear_recovery_21.jpg Loaded the gear and the unmanaged mass of paper tape on, sort it out later! http://www.surfacezero.com/g503/data/4173/gear_recovery_22.jpg There were removalists boxes of documentation, so many I had no chance to go through more than half a dozen. In the ones I went through, I found manuals for the Fox 2, DEC printsets, printset for the 11/05, PDP-9 manuals, Honeywell 716 and Westinghouse manuals. I found a CDC disc pack that seems to be suitable for an RM03. Once again no PDP-9 (that I could identify as such!), peripherals or any other piece of hardware that these manuals were for was evident anywhere (I looked!!). No sign of any early DEC units such as RP01 02 03 or the like, nor PC04 or anything. http://www.surfacezero.com/g503/data/4173/gear_recovery_23.jpg After looking at the Foxboro documentation it seems the Fox 2 ran an application called 'FOXY' which controlled the coking oxygenation plant at Port Kembla steelworks from about 1972 to the mid-late 1970s. Documents indicated the PDP-9 controlled the steelworks plate rolling mill. I have no idea (yet) what the Honeywell and Westinghouse machines did. One curious thing was, I was allowed to take the machines, documentation and so on, but not the rack slides nor any part of them. They were to stay with the cabinets. Yes I did mention they were specific to the equipment and probably no use for any newer equipment. So it's going to be another long process of making or adapting rack slides as I have already been doing for my other gear. As soon as I had finished loading I left gor home. After an overnight rest stop near a nice lake, I was back home in Brisbane on Sunday arvo. Here is the haul before I started unloading: http://www.surfacezero.com/g503/data/4173/gear_recovery_24.jpg http://www.surfacezero.com/g503/data/4173/gear_recovery_25.jpg I've contacted others about the need to recover the rest of the gear and especially the boxes, so I'll see what happens in that respect. I must thank Jay for putting me in touch with the relevant people. All in all it was I think a worthwhile 1651km (1025 mile) round trip! Steve. (Top posting my reply here - yes I don't normally do it nor condone it, but it in this case suited my lengthy post) ---------------------------- Original Message ---------------------------- Subject: Unidentified DEC gear available, NSW-AU From: "Jay West" <jwest at classiccmp.org> Date: Fri, January 29, 2016 6:11 am To: cctalk at classiccmp.org --------------------------------------------------------------------------
