PDP-11/35 power supply woes

by barryc＠rjlsystems.com

Look on the bright side - there's no plywood or MDF. I once picked up an arcade cabinet from a guy without realizing that a mischief of mice had made it their home while it was in long-term storage. As gross as I'm sure that power supply was when you first opened it up.... You may think you can clean years of mouse urine out of MDF.... and I'm willing to grant the possibility that it may actually be theoretically possible. but I eventually had to give up and put the cabinet at the curb. ------------------------------ Message: 28 Date: Mon, 14 May 2012 00:01:34 -0700 From: Seth Morabito<lists at loomcom.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: PDP-11/35 power supply woes Message-ID:<9B95838A-9A34-4296-A18D-5107E43D9A99 at loomcom.com> Content-Type: text/plain; charset=us-ascii Ugh. It was a fairly disappointing day on the PDP-11/35 restoration front. I've updated my restoration journal (http://www.loomcom.com/projects/pdp11-35/index.html ), but in summary, my H750 power supply is one big gross mess. Take a look at the condition it was in: http://www.loomcom.com/projects/pdp11-35/bc05t_rust.jpg http://www.loomcom.com/projects/pdp11-35/h750_out.jpg http://www.loomcom.com/projects/pdp11-35/h744_messy.jpg http://www.loomcom.com/projects/pdp11-35/h744_corrosion.jpg http://www.loomcom.com/projects/pdp11-35/xformer_mice.jpg http://www.loomcom.com/projects/pdp11-35/rusted_parts.jpg All that pink stuff is fiberglass insulation. Mice got into the power supply, and made it a nest and toilet. Everything is soiled, and lots of exposed metal is corroded. I'm feeling kind of low about this. I do believe this is restorable, but the amount of time it's going to take is bumming me out. I'll have to disassemble everything, right down to the last screw, and clean anything that's cleanable, strip rust off of anything strippable, and test all the parts individually. The fan will probably need to be replaced. Plus, it's just yucky, y'know? At least I've cleaned out the mouse nests. That's a start, I guess. -Seth -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

DigiDesign DSP cards

Oh my! http://www.distributed.net/Main_Page As far as I know, there is no DSP56k client, but there are CUDA and STREAM clients so in principle it should be possible. I hope to one day have time and expertise to update the NeXT client to use the NeXT DSP56k, just because it's about the last practical compute effort my NeXT can contribute to and the DSP56k would probably about double its keyrate. Your PowerMac would be way more powerful. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

S-100 IDE V2 board PCBs

by LYNCHAJ＠YAHOO.COM

Hi I reordered the S-100 IDE V2 board PCBs due to numerous requests. There are some extras available so if you would like one or more PCBs please let me know. The S-100 IDE V2 board PCBs are $20 each plus $3 shipping in the US and $6 elsewhere. These PCBs are probably our most popular board and are going quickly. Please send a PayPal to LYNCHAJ at YAHOO.COM including your shipping address.

For shipping: dead Apple Powerbook AC adaptors and battery charger

by mtapley＠swri.edu

All, disposing of 3 dead Apple AC adaptors. Would love to fix them, but have higher priority repairs to make and have already ordered replacements (FastMac TruePower 65W for Powerbook G3, per a recommendation on LowEndMac; will post results if anyone is curious). I suspect these are e-waste, but in case anyone with more time or sense of history than me needs them, thought I'd make them available here first. Shipping from Texas, USA, area code 78254; I'll include the (IEC C13?) cord that goes from the wart to the wall only if you request it, since I can use those and you may want to save on shipping. 1) Powerbook Duo AC adaptor, model AA19200, Apple family number M2693. Output 24V, 1.5A, plug fits our Powerbook 3400's and presumably other powerbooks as well. Our 3400's now refuse to run or charge from it. 2) Macintosh Powerbook 45W Power Adaptor, Model Number 3037. Output 24V, 1.87 A. This one looks a lot like the power adaptors that came with the 3400's, but the connector on its cable is a much narrower barrel with no central pin. It is possible this one works. 2a) "VST Charger 500 for Apple Powerbook 5300 & 190 Series batteries; Requires Apple or VST AC or AC/DC adaptor. DC in 24V 2.0 A." Connector matches 2) above (the narrow barrel) so it would be a good idea to take these together; accepts two battery packs for PB 190/5300/3400 on top. This one emitted magic smoke simultaneous with ceasing to work, so it will definitely need parts replaced. 3) "Macintosh Powerbook 45W AC Adapter" Output 24V, 1.88A. This one has the larger connector that fits the 3400s. I tried to open it, so the label is a bit torn up. Our 3400's refuse to run or charge from this one. Please send email to me (best) or the list, or contact me at cellphone number below. I'll wait until May 20 or so before tossing these. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.
