Hey all -- I've started stripping down the "fire-sale" PDP-11/45 I picked up in November, in preparation for sanding and repainting the rack and processor chassis. There were two H742a supplies in the rack that I believe are too far gone to be reasonably restored (in particular the heat definitely did a number on at least one of the transformers) and I have a pair of H7420a's ready to take their place. I hate to see things go to waste, though, and even though it's probably pointless -- before I send these off to the scrapyard, I wanted to check to see if anyone here needed any parts. Shipping the whole unit(s) would be pretty expensive, local pickup is an option if you want the whole thing(s). The transformers are a bit toasty but the power supply boards look like they might be usable after a good cleaning and testing. Fans are dead (either melted away entirely or rusted out). I suppose there's not really much else that'd be useful to anyone but I have a compulsion to make sure...
Here's a couple of pictures: https://1drv.ms/u/s!Aqb36sqnCIfMpL89R2GtJFrrRqZ1vQ?e=Re3KZr And for fun, here's a bunch of pictures of the unit just prior to the teardown: https://1drv.ms/u/s!Aqb36sqnCIfMpL8-mTCp-NndzDTpbw?e=8aWCl4 (I do think there's a good chance this will run again, the major casualties were the front panel, power supplies, and wiring harness. I have replacements for the first two, and the third is just a matter of taking the time to build a new one. The boards cleaned up nicely and there's no real damage to the processor backplane, amazingly.) - Josh
