VAX-11/750 registry (Was: Reviving a VAX-11/750)

by bob＠jfcl.com

> But with an rdbms and a nice front then it could encompass all makes and models. Linux, a web page form, some PHP scripts and MySQL and we're done. Any volunteers ??? :-) One problem is going to be authentication. If it has any contact information (and it seems like it would need to in order to be useful) then it's gonna become a target for SPAM. Bob

PDP 11 - how to lock heads in a rx01 and rx02 - seeking advice

by jnc＠mercury.lcs.mit.edu

> From: devin davison > I was told to lock the heads in the rx01 and rx02 drives. Err, I think we told you to lock the heads the RL0x's, not RX0x's; the former use large rigid packs, the latter are 8" floppy drives. AFAIK, there is no need to lock RX heads when moving them - there is nothing in the manual about RX drives being shipped from DEC with the heads locks. > are there any good guides or sites with lots of pictures of the drives > taken from different angles apart so i can get a better idea of what im > going to be working with? Not that I know of, but the DEC manuals (mostly available online) are adequate. > Also, people tell me getting the drives off the rails and out of the > rack is a pain, where would i find the appropriate information on how > to do that? See above. > I really don't want to take the drives out of the rack, but if it comes > to it, i would like to know how. That's very wise - my last removal, it _really_ helped that I had read the DEC manuals before-hand, as I wound up performing a removal I hadn't planned on, and that had a tricky step I probably never would have found on my own, but which I had luckily read about in the manuals. Good luck on the move! Noel

Fwd: [SunRay-Users] Surplus SunRay 2 and SunRay 3

by toby＠telegraphics.com.au

via The Rescue List ---------- Forwarded message ---------- From: Aaron Browne <gopodge at gmail.com> Date: Wed, Jul 1, 2015 at 7:43 PM Subject: [SunRay-Users] Surplus SunRay 2 and SunRay 3 Units - Victoria/Australia To: SunRay-Users mailing list <sunray-users at filibeto.org> The company I work for is about to undertake a total endpoint replacement. We are replacing all of our SunRay 2 and SunRay 3 devices - hundreds of units of both types. All units are in working order. Is anyone interested in providing a new home for any of these devices? Otherwise, they are going to be recycled. Victoria/Australia is preferred destination but we can talk other parts of Australia if required.

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > It appears the top edge projects further than the bottom by a tiny bit > leading to a tapered appearance, but I assume the plane of the printed > inset panel is parallel to the exterior mounting surfaces. By top edge I assume you mean the top edge of the unit (we need a common term for the entire injection-molded plastic thingy), as it would be when mounted on the rack? And the distance you're talking about is the distance from the very front of the unit to the flange that projects out around the unit on three sides (sides and bottom), right? OK, I'm measuring mine (with calipers :-), and from the back of the flange to the front of the rim around the coloured insert, it is 3.80 cm at the top, and... 3.80 cm at the bottom. So no tapering. (And it's the same on both sides.) > A common method of determining radii is to use an engineers radius > guage. Which I don't happen to have... something to add to my tool wish-list! :-) > Failing that, try fitting a series of circular objects (coins etc.) > which can then be measured with calipers or micrometer. I did try with the butt ends of a number of large drill bits, but I didn't get really good results. I mean, you can tell when it's way off (too small, and the object 'lifts' off the surface at the outer edges of the object, too large, and you get a gap in the middle), but there's a range in the middle where it's hard to tell - it all depends on where you decide the ends of the curved part are. Oh, one note: when I gave the gap between the coloured insert, and the sides of depression it sits in ("it's slightly smaller than the inset in the plastic housing, by about .5 mm"), that .5 mm is on each side, not total.

I have requests from several list members to stop b y and do some shopping/ trading. I'm still on the mend from my latest replacement shoulder and will be out of commission for quite a while yet. While not quite up to the show, I have no problem with members stopping by. But I still have doctors appointments, PT, etc. I can see I-74 from my house and am about 10 miles west of I-57 by Champaign, IL. There are several good routes to Chicago from here, which is about a 3 hour drive. If anyone wants to stop by I only ask that you make a ball park appointment that will not interfere with my medical appointments. If I have an idea of what you want (LA120s, monitors, other large things) I can have it out and ready. I should be able to have some of my high school helpers to help pack and load. I'm not a morning person, but can make it work. Nighttime doesn't bother me at all. If I missed anything or have general comments, please reply. If you want to set up a time or have specific questions, please contact me off list. Many Thanks, Paul

CDC disk drives (was Re: what IBM system is this?)

During my mid- to late-80s tenure at Georgia Tech, we had 2 x Cyber 180/855, 2 x Cyber 180/830 and 1 x Cyber 180/990. I'll have to ask around for someone with better memory than me as to how many, but we had quite an ocean of disks. KJ

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > a replica PDP11 masthead panel for the DEC H960 rack. That would be great! (I'd buy one! Or more!) But how are you going to produce the plastic housing? I suspect that's going to be harder than the inset coloured panel. > I need some help from the list, if possible - I would like the > dimensions of the width and height. The inset (the coloured part) is 8.45 cm high (it's slightly smaller than the inset in the plastic housing, by about .5 mm); alas, I don't have a metric ruler long enough to measure the width directly, but in Imperial it's 3-21/64" by 18-9/16". I don't have a good way to accurately measure the radius in the corners, but it seems to be about 8.5 to 9.5 mm. > I also would like to know of the outer edge of the masthead is a beige > colour, or even silver. The raised edge around the inset panel is painted a dull silver - like the old silver paint, but with a touch of grey in it. The edge itself is 4.1mm wide, according to my calipers. > The panel would be the inner bit with the radiused corners, the edges > being a seperately cut panel which is in front of the the detailed one. Not sure I follow this? The entire top unit, including the raised edge around the coloured inset, is a moderately complex injection moulded plastic piece; behind the front, it's kind of like a box that's open at the back, and there's a ridge around the back edge on three sides; the bottom edge is shorter, and the top edge is extended further back. Finally, there are a couple of internal tabs where it actually connects to the H960. If you want an original to copy, TopLine has one for sale on eBay (ignore the ridiculous price they've got on it, they are very reasonable). > I would also like to know how deep the recess is for the front. I > suspect the same as the filler panel bezel edge, about 3mm. 4.0 mm by my 0.5 mm ruler. > And also the depth of the plastic backing. You mean, how thick is the plastic in the housing? 2.7 mm in one place, 2.8 mm in another, 2.3 mm in a third? Interestingly, IYWR, in previous thread we'd mentioned how other people produced their own insets; one for a terminal server, and one for the LISP Machine. I looked at my LISP Machine one, which I had assumed was in a similar housing, but it's not! It does indeed fit on an H960 (the early LISP Machines were built in H960's), but it's quite different. It's in an extruded aluminium unit (of constant cross-section), with no end pieces (although the bottom plate has small squared cut out of the corners); the extrusion's cross-section is exact a capital 'F', but upside down. There are little square 'serifs' on the 'back' of the 'F' (the front side, when installed), and the printed panel fits in between them. Now that I look at it, it looks very similar to me to some things I seem to vaguely recall being used on earlier DEC machines (either a PDP-6, or a KA-10, I don't recall where it looks familar from). It being a more-expensive aluminium extrusion makes sense; that was back when that sort of thing (along with lots of lights! :-) was acceptable. Noel
