So I think I need to upgrade to a real Soldapullt instead of the RadioShack special. Is the slimline III model as good as the original bulky one? I don't mind the xtra pressure to push down the plunger on the original, I'm concerned with the effectiveness and ability to get in tight places my Hakko FR gun can't fit easily or when it's not worth changing tips for a single different component. Thanks, Cheers, Corey corey cohen u??o? ???o?

Close encounters of the CADR kind

by jnc＠mercury.lcs.mit.edu

> From: Lars Brinkhoff > http://i0.wp.com/futurewavewebdevelopment.com/wp/wp-content/uploads/2016/10… That might actually be the CONS Machine (effectively a prototype CADR); Greenblatt looks awfully young in that picture! Also, I don't recall him being super-involved in the CADR work. (You might ask him which it is!) The CONS CPU backplane is apparently now at the CHM: http://www.computerhistory.org/collections/catalog/102647223 My memory of the CONS machine is that, like the Chess Machine, it was a special purpose CPU hung off the AI PDP-10. (Or maybe the Chess Machine was attached to MC? I forget.) However, while that may have been its state early on, in reviewing some CONS documents I discovered that it was eventually given a keyboard and display, although it did remain hooked up to the PDP-10. The CONS machine is described in 3 AI Lab publications: Working Paper #79, Working Paper #80 ("CONS", by Tom Knight), and Memo #444 ("LISP Machine Progress Report"), The first is available here: http://www.textfiles.com/bitsavers/pdf/mit/cadr/Greenblatt-The_LISP_Machine… but it's just an architecture document. Memo #444 has an extensive "Current Status - August 1977" section, which gives more info about the CONS machine as built. Noel

What's the rarest or most unusual computer-related item do you own?

I have two Sun 386i systems. It has an Intel 386 processor and runs SunOS. Not exactly a big seller for Sun. I met some of the designers at the Vintage Computer Festival East 2.0 in Burlington, MA. -- Michael Thompson

What's the rarest or most unusual computer-related item do you own? [Tek 4132]

From: allison <ajp166 at verizon.net> > >The 32016 was not clocked very fast nor did it have any pipelines to >speak of. True. And lots of interesting bugs; some show-stoppers in early steppings. >If the 32016 had a second generation, some tweaks and faster process it >might have had hope but like 68k and Z8000 it was good idea but late. It had 2 additional generations of general purpose procs (32332 & 32532) and a number of embedded iterations (ns32gc, ns32fx). But, yeah, too late relative to to i8086. KJ

Macintosh Plus: 31 years old this coming Monday

by cmhanson＠eschatologist.net

I met up with some friends at a coffee shop to get some data off a hard drive that was given to one of them with an old Mac Plus. During the course of this, we looked some things up, and learned that the Mac Plus was released on January 16, 1986: Thirty one years ago, as of this coming Monday. Maybe I?ll take some time out on Monday to finally fit mine with the replacement analog board that I?ve acquired, so I can enjoy that beautiful bluish-white phosphor glow once again. -- Chris

door hinges needed for hp racks

by cctalk＠snarc.net

Vintage Computer Federation just got this: http://vcfed.org/evan/hpmini.jpg We have the left/right cabinet doors, but the cabinets are missing all of the hinges where the door pins sit. Does anybody have spares?

Origins of the term 'WYSIWYG?

by ard.p850ug1＠gmail.com

Does anyone have any thoughts as to when that term, or a near equivalent was first used? The reason I ask is that I have been looking in some old photographic books and have turned up a 1954 advert for the Wrayflex (an obscure British single lens reflex camera). The text ends with : ;...through the lens focusing at any distance. No adjustment for paralax. No coupled rangefinder. Just the simple axiom ... "What you see, you get" ' I wonder what predates that usage (if anything) -tony

Need serial cabe for pdp 11/34 M7856

by jnc＠mercury.lcs.mit.edu

> From: Devin > i need a cable that is wired for serial. You mean EIA, right? (They're both serial... :-) > If no one has the cable, i could make one myself The EIA serial cables that plug into the Berg connectors are pretty much unobtainium. I have a couple that came with an 11/04 I bought, but I've never seen one for sale, individually. So yes, you are going to have to make one. Fortunately, that's not too hard! > i just need the 40 pin connector that goes on the cable. These connector (the individual wire kind, not the flat cable kind) can be found on eBay under the search term "dupont connector housing". Here's a listing for the 2x20 kind you need for a DEC serial cable: http://www.ebay.com/itm/172446135576 The same search terms should provide the pins, too. The quality will be pretty crappy, but I find working with regular electronics suppliers' sites to be too painful (for me, at least). Noel
