i evaluated the first 11/44's for use in a Tektronix product, even then we had some power supply failures. From my foggy memory, you may want to check, the power supply connector for corrosion, then check the status of the caps. Its not going to be easy to test the big ones if you don't have the equipment. Unfortunately i lost the complete set of schematics in a fire. Still think i have a CIS board which may want to get rid of -pete -----Original Message----- From: will kranz [mailto:will_kranz@SoftHome.net] Sent: Tuesday, November 04, 2003 8:44 AM To: cctech(a)classiccmp.org Subject: PDP-11/44 want list John On Tue Oct 8 20:11:58 2002, you posted about your 11/44. I was searching for help with the H7140 power supply when I came across your post. I recently tried to power up a system I got a couple years ago, and have a flashing 'DC On' indicator. I don't know how serious this is, or if I might be able to repair/adjust it with some guidance. Suggestions? I have no documentation on the power supply. Thanks.

Any suggestions for cleaning yellowed computer parts?

by sloboyko＠yahoo.com

I've had good luck buffing double-shot molded keytops back down to the original color and finish while removing a minimum amount of material. IMHO, this type of yellowing and chalkiness is not at the surface, but it must be from exposure of the plastic to ozone, UV light (flourescents?) or possibly smoke. I use metal polishing compound and a buffing wheel, then finish off with car rubbing compound. This process is tedious, but makes an _enormous_ difference in the appearance of equipment. Note, I mentioned "double shot molded"; obviously, pad printed keys (virtually every cheap keyboard made afrer 1985 is made with pad printing) is just going to come off. You need to look at the key from the bottom in order to determine this for certain. ===== -Steve Loboyko Incredible wisdom actually found in a commerical fortune cookie: "When small men cast long shadows, then it is very late in the day."

Sol-20 website update

by frustum＠pacbell.net

It has been about 11 months since the last update, but my Sol-20 site now has a ton of BASIC programs read to run on the two different dialects of PT BASIC. A gentleman by the name Ralph Hopkins sent me >500 files that he extracted from disks he had from the days of old. About 400 of them were BASIC programs. The only hitch was that he wasn't sure which programs ran or not, and in fact, which were even for the Sol. Complicating it was that Processor Tech. had two different dialects of BASIC of their own (BASIC/5 and Extended Cassette BASIC). I tried running all 400 programs and pulled the weeds (about 1/3 of them). Like a lot of BASIC programs of the era, the vast majority are turds, but there are certainly more than a few gems in the mix. The results of this effort are these two new web pages: http://www.thebattles.net/sol20/bs5_pgms.html http://www.thebattles.net/sol20/ecb_pgms.html The front door to the Sol website is, as always: http://www.thebattles.net/sol20/sol.html About 100 of the programs that Ralph submitted to me are various machine language programs and ASM. I have already gone through a lot of them, but the difficulty is in making sense of it all and organizing it in some fashion. A typical problem is that assembling the source code doesn't match the supplied binary. Eventually I'll sort it out and most of it will make it online. And Bob Stek, if you happen to read this, yes, I still have your PTDOS disks, and I haven't forgotten them. I haven't made a lot of headway on getting a helios system running, so I went and bought a catweasel card and hope to scrape the bits off the disks one way or another. That is the next project in my queue.

Any suggestions for cleaning yellowed computer parts?

by netsurfer_x1＠fastmailbox.net

I had a similar problem once. You might want to try using SoftScrub with bleach. I used that on a yellowed computer I had once. It didn't get it perfect, but it made it look a little bit better. Then again, I didn't put max effort into it, but still, thought you'd want to know.

U-haul. Message-ID: <F99DE46EAEFF4C45A1E9274DFC3C8032324275(a)bsod.bigwhitehouse.net> I have a number of HP9000/300 & 400 series computers available on a U-haul basis in seattle. I don't have an exact count of my stash, but it's somewhere on the order of: 10-15 HP 9000/425 (varying amount of memory, probably 16-64 megs) 2 HP 9000/433 (one with 128 megs, the other with 64) ~3 HP 9000/340 assorted models 1 HP 9000/360 or thereabouts. All or most of these machines are in working order. At least one of the 340s has an external SCSI interface. Take them away. Maybe offer something neat in exchange, if you so choose. I'm going to want the space soon, but I don't want to discard them; I'd rather see them return to use.

Raining Control/Interface modules (model 7020-127)

by vcf＠siconic.com

I have a mess of Rainin Control/Interface modules. They are basically lab interfaces for controlling "stuff". I have no docs, and not much more idea of what they do beyond this simple description. I imagine they have some relays or optoisolators in them. If you know what they are and want a mess of them, make me an offer (privately please). -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

glue

by kdavis＠ndx.net

I'd suggest Epoxy. Depending on your application, you can get the good stuff from boating stores. They sell the resin and hardener separately. You can get different types of harder that set quickly or over night if you need to reposition what you are working on. It's excellent for filling gaps, can be sanded, drilled, sawed or painted. If you have something like a cracked panel or faceplate, you can buy some fiberglass cloth and "paint it" with the epoxy and place it on the backside. It will be stronger than the original. http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay? storeId=10001&langId= -1&catalogId=10001&classNum=1&subdeptNum=&storeNum=&productId=28496 Kirk > > Can anyone recommend a glue for plastic that doesn't suck.
