Hey. I'm sorry for the off topic post, but I couldn't think of another forum to ask my question. I'm just looking for information as to whether there are different sizes Pentium processor dependent upon whether the processor is for a desktop or laptop. I want to see if I can give my old Hewlett Packard OmniBook a little more juice.

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

by lyokoboy0＠gmail.com

I asked for advice a while back on what to expect with moving a pdp 11, I was told to lock the heads in the rx01 and rx02 drives. I'M getting pretty lost in all the information about the drives, 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? 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? 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. I am scheduled to pick this stuff up in 5 days. --Devin

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

> 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

> 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.

VCF Midwest visitors

by useddec＠gmail.com

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?)

by seefriek＠gmail.com

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
