PDP-11/35 power supply woes

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.
