DEC BA11-K KY11-L mounting brackets -- how?

Well, if you put the bolt in first (which you'd kind of have to do, if going >from front to back, with the adapter already mounted to the KY11-L), you'd have to hold it in place while you offer the KY11-L up to the BA11-K. Which was why I was originally thinking, put the bolt in in the other direction, which you can do after you put the KY11-L+adapter in place. But that brings up another idea: put the bolt in place (on the adapter), use a first (thin) nut (with washer, if necessary) to hold it in place, then bolt the adapter to the KY11-L bezel, then mount the whole works up to the BA11-K. Not sure which would work better. I'd probably go with the 'pointing forward' bolt, and use a lock-washer (or one of those nuts with integral lock-washer), and then you can mostly tighten with a Phillips driver from the rear. But the extra washer might be easier to put together (if it doesn't push the KY11-L bezel too far forward). Noel

Might be the wrong forum to ask

by van.snyder＠sbcglobal.net

I have some old stuff, that's not really computer stuff, so this might be the wrong forum to ask. But it might be the right people. 1. Sears Model 564.21600300 monaural portable tape cassette player, with external mic and switch. It works, but it needs a new spindle belt. Tape plays, but only the capstan advances it, so it gets tangled up inside the box. I found a 5v power cube that works with it, even though it says it wants 6v. 2. Sony SVR-2000 Tivo DVR. It appears to work, but I don't have the remote, so it doesn't do anything other than cycle through its warnings about not having been connected to the telephone and made the monthly call to collect the fee. 3. Tivo Series 2 DT Digital Video Recorder, model TCD649080. Says "Welcome! Powering Up..." but I waited for half an hour and it didn't do anything else. It was connected to my network (the lights on the RJ- 45 socket were blinking) but my router couldn't see it. I have the remote for this. Any of these are yours for the price of shipping -- or local pickup in 91214. Van Snyder van.snyder at sbcglobal.net

DEC BA11-K KY11-L mounting brackets -- how?

Now that I've thought about it for a bit, I wonder if you can use a nut-and-washer in place of the press fit threaded bushing at the bottom (but otherwise all the hardware,and insertion directions, will be the same); it will be kind of difficult to get the nut in there with the KY11-L pressed up to the front of the BA11-K (which is probably why they went to the press fit threaded bushing) - maybe hold it with a pair of needle-nose? Noel PS: Thanks for the URL for the knob; I'm going to order a couple of spares (the DEC originals have a tendency to break).

The adapters on mine look _almost_ identical to yours, but _definitly_ have a #8 press fit threaded bushing at the bottom. Then there are a pair of holes in the folded-over bit, and a pair of machine screws go through superimposed holes in the flat part, and into tapped holes in the KY11-L bezel, which hold the adapter to the bezel. The 1" long #8 machine screw then holds the adapter to the tabs in the BA11-K. To do the other mounting hardware, in Henk's picture, there's a flat metal plate, with i) a hole in each end, and ii) a threaded hole in the middle. Two machine screws (#8, I thihk) hold the flat plate to the bezel, then another screw (#10, maybe) holds that U-shaped piece in Henk's picture to the flat piece, and then a pair of #10 screws hold that to the tabs in the BA11-K. (All machine screws above face forward.) >> I'm too burned out (COVID long haul) at the moment > Something a lot of us are going to have to face in the upcoming > months/years, it seems -- wishing you best!

FTAG: 42U Rack Cabinet, flat packed for collection [London, UK]

by ullbeking＠andrewnesbit.org

Hello all! I am starting a new job next week and returning to a field where my roots are (multimedia engineering, signal processing, etc). Therefore I am vacating my studio workshop and ending a few projects I was working on until recently. I have a lot of industrial and enterprise server hardware to sell or give away FTAG (free to a good home). FTAG: Toten GS Cabinet, 42u, 1000 mm Deep, 800mm Wide, 3 Fixed Shelfs + 2 Fan Units + Cable Management 800mm wide which is easier to work with than a 600mm. However being 1000mm deep it does it mean you can add 670mm servers. It's a relatively large cabinet so you can fit pretty much most rack-mountable servers. It is packaged as a flat-packaged self-assemble rack cabinet in five large, flat-packaged, boxes. I will of course help move them from my office to your van (I recommend collection with a van or courier with van). This item is among the first things I'm giving away because I need to free up some room. This will make it easier to catalog and sell/give away. I will be advertising other items too in the next few days. Post code: N15 4QL (Seven Sisters and Tottenham Hale) Any recommendations for other mailing lists or web forums to advertize this offer are welcome too. Thank you all!! Kind regards, Andrew

DEC BA11-K KY11-L mounting brackets -- how?

by fritzm＠fritzm.org

Hi all, I'm reassembling an PDP-11/34 in a BA11-K chassis right now, and am a little puzzled by the front mounting brackets (the ones that hold a KY11-L of either sort on the bottom, and a half trim-panel on the top). In particular, on the bottom half, the available place for screws to go to attach the bracket to the chassis is nearly completely blinded by an overhanging tab. The engineering drawings I've seen are unfortunately not very clear on this... Anybody have an 11/34 in a BA11-K and care to take a peek and tell me how the hardware here is properly configured? (Hex head instead of DEC's ubiquitous Phillips truss, to allow tightening from the side? Machine screw from back, and a nut on the front? Other?) cheers, --FritzM.

Well, I have an KY11-LA mounted on a BA11-K; the KY11-LA and -LB use the same bezel, and should have identical hardware. There's an intermediate 10" or so high adapter piece (one either side, of course) mounted to the KY11-L. (That's attached to the KY11-L with short machine screws which are inserted from the rear, and go into tapped holes in the KY11-L bezel.) That piece attaches to the BA11-K with different hardware at the top and bottom: on the bottom, a single 1" or so machine screw (#8, I think) goes through the vertical tab on the side at the front of the BA11, to a tapped hole in the adapter piece. At the top, a pair of short countersunk machine screws (#10, I think - definitely larger than the 1" machine screw at the bottom) attach a pair (one each side) of those black plastic mounting widgets which have a pair of balls on stalks; those go into holes on the back of the blank panels, and those screw also hold the adapter piece to the BA11-L at the top. (I looked for the DEC formal name for those pieces, but couldn't find it.) > I'll get some pictures of the brackets I have, too -- maybe they aren't > the standard/correct ones for an 11/34... I'll take a look. I'm too burned out (COVID long haul) at the moment to take pictures or do a drawing right at the moment; if needed, I can do it tomorrow (or so). Noel PS: A while back you were after measurements on the KY11-L power knob; did you ever get those: If not, I've got one, and can measure it.

"Check this document 123-456-78 in bitsavers, page 26". Yeah, I didn't try and pass a URL, too hard; (and in any case, a tricky con artist could point to a fake document they had posted).

Yes, the PC05 is for the PDP-11 (and others): https://gunkies.org/wiki/PC04/PC05_High-Speed_Paper-Tape_Reader/Punch Yes, what I _should_ have done is say 'the PC05 is for the PDP-11; the PC04 (which this is) won't work on a PDP-11. If a PDP-11 owner buys this for his PDP-11, he'll probably by unhappy'. Noel

eBay sellers

by jnc＠mercury.lcs.mit.edu

I'm slightly amazed at how some eBay sellers react. Take this item: https://www.ebay.com/itm/154404969351 which the seller had listed as a 'PDP-8 PC05'. I sent the person a message pointing out that it was a PC04 (as shown by the 4 rocker switches, and the small backplane - PC05's have a larger one to hold more cards). They sent a nice peply, but didn't alter their listing! Well, I hope the bider really is a PDP-8 owner who wants a PC04... :-) Noel

Looking for video (or photos) depicting how to remove ASR 33 printer from keyboard

by billdegnan＠gmail.com

I am looking for a video or photos that show how one removes the printer >from the keyboard safely on an ASR 33. I need to get to the underside of the printer levers so I can re-align them. I am getting incorrect characters when I type over half of the keys. I can see that a few levers are out of whack or not seated correctly but I believe to get to them properly I need to put the printer on its side or under a lift to get to the underside. I am nervous about detaching the "H" shaped gizmo that connects the keyboard to the printer. Thanks Bill

VCF Midwest 16 Date Announcement

by silent700＠gmail.com

Hello computer friends - all of us down in VCF Midwest Planning Bunker have decided: VCFMW16 planning must commence! To not do so would surely set up for failure, if and when conditions continue their current upward trend and we get the OK to gather again in unlimited numbers. So...we're going to have a show! Our schedule this year will be the same weekend as in 2019, with the dates this year falling on the 11th and 12th of September. Same location as well, at Waterford Banquets (and Clarion Inn), Elmhurst, Illinois. See our full announcement here: http://vcfmw.org/announce. And fill out the linked survey if you'd like. Still much to do - room block reservation, improved table layout planning, speaker recruitment....and that dang T-shirt. We hope everyone who is able to travel in September will consider paying us a visit. More news to come - check our newly re-themed website for updates as they occur! http://vcfmw.org -jt

Mitsubishi Melcard (edge connect type)

Does anyone recall what kind of hardware/software was used to read/write the early Mitsubishi Melcard EPROM cards with the PCB edge connector contacts? It was explained to me by someone that a EPROM programmer could be used, however I've never seen a socket which fits the edge card connector of these cards. I've uploaded an image of the edge contact end of this type of card here: http://www.hammondorganservice.com/downloads/images/melcard.jpg Seems these were also available in the SRAM variety as well.

Apollo Date Bug

by knowak＠alumni.calpoly.edu

Hi All, Back after a long time away from this list... I happen to have a small herd of Apollo DN3500/4500 boxen which i pulled out the other day to see if they still run. Sure enough they still boot up (one has a flaky PS but i have a few spares). Anyway, the last time i fired one of them up (runs SR 10.4.1) was around 2015 and it still was able to deal with the current date back then. This last time the other day I did an EX CALENDAR to reset the date to the current date and it defaulted to some date in 2015 again and i wasn't even able to log on using my known login. I figured it was due to the well known date bug so i reset the date back to 2013 (of course it warned me about possible duplicate file IDs, etc) but I was able to log in again. My question, has there been any progress in fixing the date bug by anyone (who still has some of these machines) (I'm thinking guys like R. Stricklin..). Or is this pretty much a dead end? I know HP put out a "patch" which according to Jim Rees's page was never really an effective patch to begin with...Any insight would be appreciated. -Kurt
