Up for sale is a 6487143 IBM Power Supply Board Standard Vintage Genuine FOR PARTS REPAIR UNTESTED.  This was purchased in an IBM lot and I have no way to test it, so I'm just listing it for parts or repair.  I'm pricing it low, because of that.  I can't find another one for sale on Ebay and only could find one for sale on a website for $237, so this should be a great deal.  It looks in great shape and I'm not seeing any issues visually.  I hope this finds someone who gets good use out of it.  Take a good look at the pictures and see what you think.  I'm pricing this low and paying for the shipping, which will be more with the increases.  I may ship with FedEx or UPS, depending on the buyer's location.  I ship within 24 hours of receiving payment.  If you have any questions except offers, feel free to ask before buying.
