Looking for some DEC-related spares..

Well, a later poster mentioned a possible source of new feet - I had assumed you wanted exactly identical ones, which may not be available, but if all you want is functionality, you can probably find that from the sources they provided. > I have found a little 4 slot Qbus box with 3 swtiches on the front, > these seem to be the same mechanisms behind the toggles. Yes, they are: I fixed an 11/05 front panel with switches sourced from one of those 11/03 front panels. I hated to do it, but the 11/03 panel was a spare, and as you say, if the switches ever re-appear, I can repair it. Noel

> From: tony duell > 2 of said feet got bent at right-angles (!) Hammer them straight, and clean up the threads with a die. Those outriggers are unobtainium, so I can't imagine the feet are much better. > switch mechanisms for the PDP11/45 front panel. I have the toggles > (thankfully), I need the switches Now you're really into unobtainium territory. We've been moaning about the inability to find these for a while now. All the early 11's (except the 11/20) use these - 11/05, 11/40, 11/45, etc - and a bunch of us need them, but nothing doing. Noel

Honeywell/Bull DPS-6 deskside info?

by derschjo＠gmail.com

Along with the 11/44 I also picked up a Honeywell/Bull DPS-6 deskside workstation; I can't seem to dig up much information specific to this model (a badge on the rear labels it as "Model/Index No. B01732"). I can take some detailed pictures later this week after I've had time to clean it up (it's very, very dirty), but it looks very similar to the DPS-6 unit pictured on this site: http://www.feb-patrimoine.com/projet/gcos6/gcos6.htm Anyone have any docs on this thing? Or fun anecdotes to share? What have I gotten myself into with this thing? Thanks, Josh

Is tape dead?

by c.murray.mccullough＠gmail.com

I came across a fascinating article by Evan Koblentz in TechRepublic Daily Digest today entitled: ?Tape isn't dying -- it's getting healthier and smarter?. Does this mean my ADAM tape drive system has a future after all? Naw! But one can wish. Are there tape systems in the PDP family, et. al., still running? Happy computing. Murray :)

Moving PDP 11 gear - Status update

by lyokoboy0＠gmail.com

Hello. It has been a while since i have posted anything on this list. Last time i posted i was asking advice on how to properly load up and move a pdp 11 with related gear. It has been quite some time since i picked all this stuff up and figured i would give a status update here to let others know my progress with the machine. Images of what I picked up can be posted later if there is interest. In total i picked up the following: 2 racks containing - a pdp 11/34 2 RL02 drives A RL01 Drive 2 complete vt 100 terminals 2 large line printers a second empty 11/34 . no cards. second rack contains a large tape drive. Piles of tapes and rl02 disks. I have yet to inventory them all. Most are labled with aircraft names. The machine was used to recover flight data recorder info, so i imagine that is what is on most of the tapes. Lots of RSX docs and related tapes. I had the machine fired up for an hour or two, i was messing with the front panel when i heard a fizzing sound followed by a burning smell. The front panel is no longer responsive. I have been going over the power supply. Mr Paul Anderson on the list here has been generously been giving much of his spare time assisting me on the phone with troubleshooting the power supply. Thats my progress so far. Kinda taunting that i moved it all the way over here and it does not even work yet, but hopefully soon i can get it to work again. Lastly, the line printers were thrown in at the last moment, i was not sure i was even going to be able to fit them in the van. Due to their weight i have not been able to move them from where they were sat down since they were picked up back in july. If anyone is interested in them, i can let them go for cheap. I just do not have the space for them both, but the seller was going to throw them out if i did not take them. Ill post back with the model #'s and a couple pictures. --Devin

Amstrad CPC6128 joins the rest home

by terry＠webweavers.co.nz

It's a busy life nowadays but never too busy to kit out a newly-acquired Amstrad CPC6128. http://www.classic-computers.org.nz/blog/2015-09-24-amstrad6128-acquire-fix… for those who might be interested. It's the first time I've played with those 3 inch disks. Tez
