pinouts for LH Research Super-Mite and Mighty-Mite-A sense connectors

by aek＠bitsavers.org

I'm working on documenting these supplies, since there seems to be almost nothing on them on the web of use. There is a list of what is on the 9 pin molex on the SM, but no actual pinout. Same for the 15 pin D on the MMA, but at least there are enough pictures around to be able to assume the sense lines are on 1 and 2. The general form of the part numbers for them starts with 2 or 3 letters (TM,MM,MMA,SM) a rough power rating code (1-7) and the number of outputs (1-5) a dash, then model number probably encoding supply outputs/amps. This is based on looking at a bunch of eBay pictures. They want waaaay too much money for them on there. This all started because I need to fix the MM72s for the Alto. I got the four I took a look at fixed by replacing all of the 19000uF/7.5v caps. All of them were dried out. Not a huge surprise since they were from around 1978. Measured the rest of the caps in them with an in circuit capacitance/ESR meter and they were all reasonable, even the 1400uf/200v ones, which I had some spares for, but are much harder to find in the right size than the 19mF ones. Switching supplies from the mid 70's are NOISY (10-20mV on all four supplies)

HP 9000 Model 550 sold on eBay

by glen.slick＠gmail.com

I was wondering if this item would attract much attention. http://www.ebay.com/itm/262642624725 Sold for $787 this evening. I don't know anything about these systems. Looks interesting, but this bit of text didn't sound too encouraging: "The 550s have not held up particularly well over time. As of 2013, the museum had two units. Both units have non-functioning power supplies. The system control boards are also subject to damage from battery corrosion." http://www.hpmuseum.net/display_item.php?hw=581 Also this bit of text about the HP-UX 5.0 Operating System: "The downloadable file is an image of the system software tape for HP-UX on 500 Series computers. It was made from a 150ft tape. We obtained 47 read errors while imaging the tape, so it's probably not entirely intact, and we don't have a working 500 Series machine to check. However, the file contents of the tape are readable by issuing the BASIC CAT command from a 300 Series computer." http://hpmuseum.net/display_item.php?sw=534 Just curious if anyone knows much about these systems and if anyone has one in working condition. What might the chances be for whoever bought this system to get it into any sort of working setup? Does anyone else have software for these squirreled away in their collections?

I have been keeping a registry of key machines.. Apple IIs and Altairs and such.. whenever a serial number is available I try to record it. ?Ive only seen one or two come up twice.. and I think one was the vintagecomputermuseum guy. ?I'll keep keeping tabs and see just for fun if stuff is in fac recycling. :) Sent from my Samsung device -------- Original message -------- From: william degnan <billdegnan at gmail.com> Date: 2016-10-02 1:37 PM (GMT-08:00) To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: ka... ching!

People have been horders of computers since companies first started letting employees to take them home after depreciation.? Plenty is still out there. I still want to got to Cuba to find a Univac there.? I have this feeling that some thought-lost vintage machines are to be found there. b

11/35 on eBait

by jnc＠mercury.lcs.mit.edu

So there's another 11/35 up on eBait: http://www.ebay.com/itm/142135416325 10-1/2 'desktop' cabinet. It does have the semi-mythical KE11-F, from what I can see. Not sure what the group of 4 quad cards is (none of the pictures show the numbers clearly) - maybe an RK11-D, if we can believe the tape along the edge? Does have a couple of DL11's, and one 16KB core memory group. Noel

Come on! there are still treasures to be found! ( probaby not the 57 chevy though) In a message dated 10/1/2016 4:06:55 P.M.

Well before our time, Van Gogh paintings could be had for a bottle of wine.

I second what Mike says, Chuck. I don't enjoy fighting with these deep pocketed 'collectors', especiallu knowing a lot of this stuff is destined for a trophy case never to be used. ?But.. that's the free market. ?Plus high prices ensure I'm not able to immediately fill my basement. :) I actually find myself more excited by reproduction.. I think as cool as it would have been to own an original TVT building one myself has really made it special. ?Along the way I keep finding new potential projects. ? ?

You're one of the most prolific sources of information and helpful advice in this hobby, across almost all platforms, and you would be sorely missed indeed. Obviously I don't have anything close to what you have to contribute, but my reasons for spending time on these lists & forums are more or less the same (as well as the hope of regaining some space in my house ;-). For various reasons I've also from time to time reflected on why I waste so much time on what is just old junk to most people; someone here (Al? Fred?) once asked rhetorically how much money or lost income we spend just storing this crap, and that in particular hit home. I did get rid of a fair bit of stuff after the unpleasantness on the Vintage Forum and have cut back a lot on the time I spend on the various lists, but when I consider 'getting out of the racket' completely the friends I've made and the occasional opportunity to actually help someone with a hard-to-find item or even a piece of advice have kept me 'in it' after all. Please don't go! m

equipment available - NH

by jwest＠classiccmp.org

I have no idea how many people this person emailed, but I did get emailed directly about it so passing it on.. "Stuff" available (as of today for sure) in central NH. See a few pictures at www.ezwind.net/nh <http://www.ezwind.net/nh> The person said it includes 2 or 3 systems (altos? PDP? Vax?), and a lot of documentation and media. Some other documentation is present for other systems (Honeywell, etc.). They also said some Prime manuals but not sure I buy that. Snippets in email I received: You would not want to see what I have go into the dump. My Dad was a programmer from day until . His life's work is in my basement. Includes a VAX and a Dec PC and an Altos. Also have numerous PDP and PDP material. Many VAX/VMS manuals, multitude of software and manuals. And. We have some PDP=10 and somePDP11 books and manuals. Prime. And. Still available. Location Central NH. Come get it or call me via telephone. Where do you want it shipped and can you pay for freight charge? Want it gone now as soon as possible. Thank you. And. Here are pics of the DEC machines and an Altos. All of the documentation goes with the computers and some is from other mid-range platforms. Some text books as well. I need to sell all of this stuff to an interested buyer. Moving and can't take it with me. If you are serious (and able) to get this equipment within a week or two, then contact me off-list and I'll send an introduction email. Whoever takes this on should be in the NorthEastern US at least.. Best, J
